Pizza is a dish of Italian origin consisting of a
usually round, flat base of leavened wheat-based dough topped with
tomatoes, cheese, and often various other ingredients (such as various
types of sausage, anchovies, mushrooms, onions, olives, vegetables,
meat, ham, etc.), which is then baked at a high temperature,
traditionally in a wood-fired oven. A small pizza is sometimes called a
pizzetta. A person who makes pizza is known as a pizzaiolo.
