Pizza is a savoury dish of Italian origin, consisting of a usually round, flattened base of leavened wheat-based dough topped with tomatoes, cheese, and various other ingredients baked at a high temperature in a traditionally wood-fired oven. In formal settings, like a restaurant, pizza is eaten with knife and fork, but in casual settings it is cut into wedges to be eaten while held in the hand. Small pizzas are sometimes called pizzettas.
