For our vegetarian brunch feast, our main dishes are:
Asian Salad with Edamame (like a pasta salad, but done Asian-style. Very tasty).
Risotto Cakes with Kalamata Olives and Artichoke Hearts (funnily enough, I normally hate kalamata olives and artichoke hearts, but the Disney chefs are so amazing that I actually loved this dish! Risotto is often made with chicken broth, but Disney made ours vegetarian, and it was delicious. The olives give enough salt, and the artichokes made it buttery. MMMM).
Penne Pasta with Artichoke Olive Oil and Julienne Vegetables (I hate weddings/events where the only vegetarian option is pasta with vegetables. So boring, so uncreative, usually not very tasty. But Disney did a nice job, and it's a good dish to satisfy most people).
On the side, we'll also have Yukon Gold Roasted Potatoes, Mickey Roni n Cheese, bagels and cream cheese, and two stations: eggs and omelets made to order and a crepe station.
Cam, I can't remember if you're having breakfast, lunch or dinner, but I would also suggest that you talk to your chef. They came up with all the ideas for us; we just told them which ingredients were out. If you need a vegan (no eggs or cheese) dish, I'm sure they could whip something up.
