Food of Neapolitan origin.
It consists of a flattened disk of bread dough, typically topped with olive oil, tomatoes, and mozzarella cheese, baked quickly, and served hot. Pizza is eaten throughout Italy, with regional variations in toppings. Pizza came to the U.S. with Italian immigrants; the first U.S. pizzeria opened in 1905, and pizza became one of the nation's favourite foods after World War II. It is now popular worldwide.
