The Wikipedia has the following information about this codepoint:

Pizza ( PEET-sə, Italian: [ˈpittsa]; Neapolitan: [ˈpittsə]) is a dish of Italian origin consisting of a usually round, flat base of leavened wheat-based dough topped with tomato, cheese, and often various other ingredients (such as anchovies, mushrooms, onions, olives, vegetables, meat, etc.), which is then baked at a high temperature, traditionally in a wood-fired oven.

The term pizza was first recorded in the year 997 AD, in a Latin manuscript from the southern Italian town of Gaeta, in Lazio, on the border with Campania. Raffaele Esposito is often credited for creating modern pizza in Naples. In 2009, Neapolitan pizza was registered with the European Union as a traditional speciality guaranteed dish. In 2017, the art of making Neapolitan pizza was added to UNESCO's list of intangible cultural heritage.

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. 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.

In 2017, the world pizza market was US$128 billion, and in the US it was $44 billion spread over 76,000 pizzerias. Overall, 13% of the U.S. population aged two years and over consumed pizza on any given day.
