A taco is a traditional Mexican dish consisting of a small hand-sized corn or wheat tortilla topped with a filling. The tortilla is then folded around the filling and eaten by hand. A taco can be made with a variety of fillings, including beef, pork, chicken, seafood, vegetables, and cheese, allowing great versatility and variety. They are often garnished with various condiments, such as salsa, guacamole, or sour cream, and vegetables, such as lettuce, onion, tomatoes, and chiles. Tacos are a common form of antojitos, or Mexican street food, which have spread around the world.
Pizza is a savory dish of Italian origin consisting of a usually round, flattened base of leavened wheat-based dough topped with tomatoes, cheese, and often various other ingredients (such as anchovies, mushrooms, onions, olives, pineapple, meat, etc.) which is then baked at a high temperature, traditionally in a wood-fired oven. A small pizza is sometimes called a pizzetta.
