Here is a quiet change that reshaped Sydney’s catering industry forever.
Vegetarian sandwiches have changed from being leftovers a decade ago to being the first choice to sell out at modern catering events nowadays. Hence, this change is driven by the significant impact of improved quality, which makes plant-based options appealing to a wider audience and not just for vegetarians
And this single change should rewrite how you plan your event menu. Catering buyers who treat vegetarian dishes as an afterthought instead of the main attraction are most likely to have shortages, because these improved choices consistently sell out first.
This guide covers plant-based sandwich catering by identifying the target audience and highlighting common ingredient mistakes to avoid. It provides essential tips to ensure successful vegan catering for any event. Read more on plant-based catering in this article.
The Plant-Based Spectrum, Properly Explained
Using the term “plant-based” too broadly leads to catering mistakes. Here is a list of your possible guests at your event.
Vegetarians: They don’t eat fish, chicken, or especially meat. But they actually eat dairy and eggs. Thus, this is the biggest and most common group.
Vegans: They don’t eat any animal-based ingredients. So, this means that they’re not allowed to eat dairy, eggs, honey, or hidden animal ingredients. Thus, this is where most catering fails because these ingredients are hard to find.
Pescatarians: These types of guests don’t eat any meat or chicken, but they do actually eat seafood. Thus, people usually mistake them as vegetarians, which gives them fewer food choices than they could actually have at the buffet table.
Flexitarians: This is the largest and fastest-growing group. They eat meat but choose plant-based food when it looks delicious. They are the reason why vegetarian trays empty first, but they never show up when filling out dietary forms.
Religious and Cultural Groups: There are some guests who avoid specific meats that look like pork or beef or fast during specific times of the year. Hence, plant-based food lets them eat safely without having to explain their needs to anyone.
The main lesson here is: the number of vegetarians on your list is not the amount of plant-based food that you actually need. Because real demand is usually two to three times higher.
Why Your Ratios Are Probably Wrong
Most Sydney event planners still use an old, outdated method, in which they count the vegetarians, order just enough for them, and merely call it a day.
Try this instead.
At least 30% of your total order should be plant-based, no matter what your RSVP list is. For corporate events like in creative, tech, school, health, and government offices, you should increase that to 35% or 40%.
Then layer your declared requirements on top:
- For your vegan guests, make sure their sandwiches are clearly labeled and kept separate. It is recommended to order 1.5 times their headcount so you do not run out.
- For your vegetarian guests, they are already covered by your main plant-based orders.
- The rest of the food is for flexitarians and anyone else who thinks it looks good.
This one adjustment avoids the most common catering failure, wherein a vegan guest arrives at an empty tray because someone who eats meat took the last one. Hence, it really happens constantly, but ordering extra completely prevents it.
The Hidden Ingredients That Catch People Out
In this part, you will learn how a sandwich looks completely plant-based and still has animal-based ingredients. Here are the usual ingredients for it.
Cheese and rennet. There are a lot of traditional cheeses that are made with animal rennet. This is fine for many vegetarians out there; however, some strict vegetarians will avoid this, so it’s still advisable to double-check this with your caterer.
Mayonnaise. The usual mayonnaise has egg in it; this is why many vegetarian sandwiches that have mayonnaise are not safe for vegans.
Honey. Keep in mind that this is not vegan-friendly. Even just a tiny drop of hot honey can make a plant-based sandwich completely unsafe for your vegan guests.
Pesto. Often has parmesan.
Bread and dough. There are some breads that have milk solids, butter or egg wash. Remember to ask your caterer about this, instead of just assuming.
Worcestershire sauce and some dressings. It often contains anchovies.
Gelatine and certain additives. These ingredients are not common to find in sandwiches, but they’re usually found in side dishes and desserts.
Butter on the bread. This simple mistake can ruin your vegan sandwich.
The solution here is simple. Do not just ask for a “vegetarian option.” Instead, ask for “vegan, no dairy, no egg, and no honey.” Being specific avoids mistakes.
Building Plant-Based Sandwiches People Actually Want
The reason plant-based catering improved so dramatically is that kitchens stopped subtracting and started building. Removing meat leaves a gap. Great plant-based sandwiches fill it deliberately.
Umami is the priority. This is what meat was providing. Sun-dried tomato, roasted vegetables, olives, mushrooms, quality tomato, and slow-cooked onion all bring savoury depth.
Texture does the heavy lifting. A plant-based sandwich needs contrast to feel substantial. Crisp rocket, pickles, crunchy vegetables, and a soft bread base create the layered bite that makes it satisfying rather than flat.
Fat creates satisfaction. Olive oil, avocado, creamy cheese or a quality plant-based alternative, nuts, and rich sauces are what stop a sandwich from feeling like a salad in bread.
Acid keeps it bright. Pickles, vinaigrette, and sharp tomato and citrus cut through richness and stop the whole thing from tasting one-note.
The bread is not filler; it is structure. This is where quality shows most. A freshly baked focaccia with its airy crumb and lightly crisp crust gives a plant-based sandwich the body and presence it needs. On poor bread, a vegetable sandwich reads as light. On great bread, it reads as generous.
Menu Combinations That Work Every Time
A strong plant-based selection should span the same range as your main menu, not sit in a single lane.
The fresh classic. A Caprese-style build. Tomato, creamy cheese, basil, and olive oil. Simple, recognisable, and universally liked. This is the option that reassures cautious eaters.
The Mediterranean. Sun-dried tomato, roasted vegetables, rocket, olive oil and herbs. Bold, savoury and the one flexitarians reach for without hesitation.
The rich one. Something creamy and indulgent with jam or a sweet-savoury element. Proof that plant-based does not mean restrained.
The green one. Rocket, avocado, cucumber, and fresh herbs with a bright dressing. For the guest who wants something genuinely light.
The fully vegan hero. One standout build that is unambiguously vegan, clearly labelled, and good enough that people who eat meat choose it anyway. This is your most important item on the table.
At San San, plant-based builds such as Mediterranean and Caprese sit alongside the cured meat classics rather than in a separate corner, which is exactly how it should be. Substitutions are available on request, so builds can be adapted to specific requirements.
Events Where Plant-Based Catering Really Matters
Corporate lunches and board meetings. Small rooms make omissions obvious. Confirm requirements directly and over-order slightly.
Conferences and large functions. Undeclared plant-based demand is highest here. A 35% allocation is realistic, not generous.
Client entertaining. Serving a client a plant-based option they did not have to request is a quiet but powerful signal that you pay attention.
Team celebrations. Nobody should be eating differently at a celebration. This is where inclusive catering matters emotionally.
Sustainability-focused organisations. Plant-forward catering aligns your event with stated values. For organisations with environmental commitments, a majority plant-based spread is increasingly the expectation rather than the exception.
University, health, and government sectors. These crowds consistently run higher plant-based demand than the general average. Plan accordingly.

Frequently Asked Questions
What is the difference between vegetarian and vegan sandwich catering? Vegetarian excludes meat, poultry, and fish but generally includes dairy and eggs. Vegan excludes all animal products, including dairy, eggs, and honey. Always specify which you need, because a vegetarian sandwich is frequently not vegan.
How many plant-based sandwiches should I order? Order a minimum of 30% of your total as plant-based regardless of declared requirements, then add 1.5 times your confirmed vegan headcount as separately labelled items. Flexitarian demand is consistently underestimated.
What ingredients accidentally make a sandwich non-vegan? Mayonnaise, honey, cheese, pesto containing parmesan, butter on the bread, and breads made with milk solids or egg wash are the most common. Always confirm rather than assume.
Can plant-based sandwiches also be gluten-free? Yes. Plant-based builds can be made on gluten-free bread, which covers one of the most commonly overlooked dietary combinations. Advise both requirements when ordering.
Do plant-based options work for corporate events? Extremely well. Plant-based sandwiches are often the first to be taken at Sydney corporate events, and a strong plant-forward spread also quietly serves guests with faith-based or cultural dietary requirements.
How much notice do you need for plant-based catering? Allow 24 to 48 hours for standard orders and three to five days for larger groups or multiple specific dietary requirements.
Make the Plant-Based Option the One Everyone Wants
The best plant-based catering is not the tray nobody touches. It is the tray that runs out first because the food is genuinely that good.
