To give you an idea of what they will eat, the last week I've been here, they've eaten pizza (cheese and pepperoni), some raw carrots/tomatoes/peppers, dumplings (with egg and cheese) and strawberry sauce, donner, grilled meat, cucumber salad (but this was like pulling teeth with a few), curry with beef, the aforementioned pancakes and a lot of yogurt and musli. They will raw fruit.
Today, we made apple scones together (which was a big treat, since they're only allowed to have proper sweets on Saturdays), and I'm making veggie burgers and pasta with a vegan alfredo sauce (they've never had alfredo, so hopefully they like it? If not...). I guess my main difficulty is that a lot of comfort food for me growing up is nonexistent for them- mac n' cheese, burritos, grilled cheese, and the like.
Really, any ideas you could give me, vegan, vegetarian or otherwise would be appreciated.
PS- As for what's available, well, a fair amount of soy products (soy milk, soy pudding) and some tofus, but I haven't found faux-meat (outside of veggie burgers) or seitan or tempeh...
