Pizza or pizza pie is the name of an oven-baked bread usually covered with tomato sauce and cheese, and often with other toppings. While it is a typical dish of Neapolitan cuisine, it has become an extremely popular dish all over the world. Pizza was popularized in the U.S. after World War II, when returning soldiers from the Italian Front brought stories of the meal. October is the National Pizza Month in the United States.
Various toppings may be added, most typically:
- sauce, traditionally tomato-based
- cheese, traditionally mozzarella but often Provolone or a blend of other cheeses
- herbs and seasonings, like basil, oregano, or garlic
- vegetables such as tomatoes, bell peppers, mushrooms, red onions, chillies or olives
- meat or seafood, such as sliced sausage, (especially pepperoni or salami), ham, bacon, ground beef, anchovies, or chicken.
The crust is traditionally plain, but may also be seasoned with butter, garlic, or herbs, or stuffed with cheese. In some pizza recipes the tomato sauce is omitted (termed "white pizza"), or replaced with another sauce (usually garlic butter but sauces can also be made with spinach or onions). Pizza is normally eaten hot (typically at lunch or dinner), but leftovers are often eaten cold for breakfast or as a snack. It is famously served deep fried in batter in Scottish chip shops.
Pissa is late Vulgar Latin (9th century) flat bread, and apparently came to mean a flat bread with a cheese topping by the 14th century in some Italian dialects. Many languages around the Mediterranean have similar words meaning flat bread or unleavened bread, like 'pita'.
The Italian word for a person with a talent for making pizza is pizzaiolo. A restaurant that serves pizza is called a pizzeria (from Italian); the phrase "pizza parlor" is also used in the United States and Canada. Pizza can also be purchased in grocery stores or supermarkets (usually, but not always, frozen); in many countries, pizza can also be ordered by telephone (or, increasingly, via the Web) to be delivered, hot and ready to eat, to almost any address within range of the restaurant.
In the United Kingdom, pizza is a popular form of convenient take-away food often eaten at parties and other social gatherings.
Pizza lends itself to adaptation by other national cuisines. Examples include:
- the chicken tikka pizza
- the All Day Breakfast pizza
- barbecue pizza, with barbecue sauce instead of the traditional tomato sauce.
- cheeseburger pizza
