What kind of food do you like? Lots of great Latin American, South/East/SE Asian vegetarian food. Or you can go hippy white person food and do stir fries with tofu, seasoned baked tofu, scrambled tofu, your favourite bean with onions, a can of tomatoes and your favorite seasoning. You can also still eat vegetarian pizza 4 times a week, or do vegetarian pasta or lasagne.
Recipes depend on what you want to eat and how much effort you put into cooking, but there are all sorts of vegan recipes at
