Pizza is an oven-baked, flat, disc shaped bread usually topped with tomato sauce and mozzarella and then a selection of meats, salamis, seafood, cheeses, vegetables and herbs depending on taste and culture. Originating in Neapolitan cuisine, the dish has become popular in many different parts of the world. A shop or restaurant that primarily makes and sells pizzas is called a "pizzeria". The phrases "pizza parlor", "pizza place" and "pizza shop" are used in the United States. The term pizza pie is dialectal, and pie is used for simplicity in some contexts, such as among pizzeria staff.
