There are many kinds of pizza. One kind is Neapolitan. Neapolitan pizza was brought to the United States by Italian immigrants. This traditional pizza has a crust that is thin and crunchy. A good Neapolitan pizza has a relatively small quantity of sauce and cheese and only a few toppings. People throughout the United States enjoy this kind of pizza. Another kind of pizza is Chicago Deep Dish. The crust on this type of pizza is medium thin. It lines a deeper baking dish and then the toppings create a thick layer such that it has to be eaten with a fork. This type of pizza was the invention of Pizzeria Uno.Sicilian pizza has a somewhat thicker crust than Neapolitan and Deep Dish. Unlike other pizzas, it is not round, but is usually rectangular in shape.
