Pizza (/ˈpiːtsə/ PEET-sə, Italian: [ˈpittsa]; Neapolitan: [ˈpittsə]) is
a dish of Italian origin consisting of a flat base of leavened
wheat-based dough topped with tomato, cheese, and other ingredients,
baked at a high temperature, traditionally in a wood-fired oven. Pizza
and its variants are among the most popular foods in the world. Pizza is
sold at a variety of restaurants, including pizzerias (pizza specialty
restaurants), Mediterranean restaurants, via delivery, and as street
food.[8] In Italy, pizza served in a restaurant is presented unsliced,
and is eaten with the use of a knife and fork. In casual settings,
however, it is typically cut into slices to be eaten while held in the
hand. Pizza is also sold in grocery stores in a variety of forms,
including frozen or as kits for self-assembly. They are then cooked
using a home oven.
