What are the best vegetarian thanksgiving dishes/recipes?

I“m cooking this year—and my whole family is vegetarian. There are so many great vegetarian thanksgiving foods, but most of them are side dishes. I’m planning to make mashed sweet potatoes, wild rice, stuffed zuchini and mushrooms (thanks to some great fluther recipes). Without turkey, what can I make that might seem like a main course? No fake meat—my family doesn’t like it.
p.s. and of course, if anyone has other good veggie side dish ideas, would love to hear about them.
