Pizza is an oven-baked flat bread generally topped with tomato sauce and cheese. It is commonly supplemented with a selection of meats, vegetables and condiments.

The term was first recorded in the 10th century, in a Latin manuscript from Gaeta in Central Italy. The modern pizza was invented in Naples, Italy. Since then, the dish and its variants have become popular in many areas of the world.

In 2009, on Italy's request, Neapolitan pizza was safeguarded in the European Union as a Traditional Speciality Guaranteed dish.

Pizza is sold fresh, frozen or in portions. Various types of ovens are used to cook them and many varieties exist. Several similar dishes are prepared from ingredients commonly used in pizza preparation, such as calzone.
