Pizza is a type of food that was created in Italy. It is made by putting “Toppings” (such as cheese, sausages, pepperoni, vegetables, tomatoes, spices and herbs) over a piece of bread covered with sauce; most often tomato, but sometimes butter-based sauces are used. (The piece of bread is usually called a “pizza crust”.) Almost any kind of topping can be put over a pizza. The toppings people use are different in different parts of the world. Pizza comes from Italy, from Neapolitan cuisine, but has become popular in many parts of the world.
