The main course is just a variety of vegetables, the other is beans, because beans can take in more protein. A lot of Western food is now using tofu as a main ingredient. Most vegetarian recipes for the main dish, do Italian meals. Pasta, lasagna, or pizza, because vegetables are not the main character can be made very tasty. Vegetarians also eat a lot of dairy products, like cheese, so there are a lot of dishes with cheese. Like a vegetable casserole, which is a small pot of vegetables baked with cheese.
I had lasagna today with broccoli and cauliflower, and while normal lasagna has meat in the sandwich, we had vegetables.
