What Is Pizza?

Pizza is an oven-baked, flat, round bread typically topped with tomato sauce, cheese, and other toppings. Pizza was originally invented in Italy. Now, it is one of the most popular dishes around the world. An establishment that makes and sells pizzas is called a "pizzeria". Many varieties of pizza now exist worldwide. The crust of pizza is made from white or semolina flour and may occasionally be flavored with herbs or cheeses. Pizza crust is then sprinkled with oil or sauce, topped with cheese, and foods such as pepperoni, sausage, meatballs, peppers, onion, and anchovies are added. In restaurants, pizza can be baked in an oven with stone bricks above the heat source, an electric deck oven, a conveyor belt oven or, in the case of more expensive restaurants, a wood- or coal-fired brick oven. Pizza is also sold frozen, as round traditional pizzas or individual slices.
