Vegetarian cuisine refers to food that meets vegetarian standards by excluding meat and animal tissue products. For lacto-ovo vegetarianism (the most common type of vegetarianism in the Western world), eggs, and dairy products such as milk, and cheese are permitted. The strictest form of vegetarianism is veganism, which excludes all animal products, including dairy products as well as honey, and even some refined sugars if filtered and whitened with bone char.Vegetarian foods can be classified into several different types:Traditional foods that have always been vegetarian (Cereals/grains, fruits, vegetables, nuts, etc.)Soy products including Tofu and Tempeh are common protein sources.Textured vegetable protein (TVP), made from defatted soy flour, is often included in chili and burger recipes in place of ground meat.Meat analogues, which mimic the taste, texture, and appearance of meat and are often used in recipes that traditionally contained meat. Vegans may also use analogues for eggs and dairy products.
