Thin-crust, deep-dish, pepperoni, or pineapple—no matter how you slice it, pizza is one of America’s most iconic foods. But it wasn’t always an American staple. The modern pizza originated in Italy in the 1700s. It wasn’t until 1905 that the first pizzeria in the U.S. opened in New York City. Today, Americans eat more pizza than any other country. Cities like New York, Detroit, and Chicago serve it with their own twist. Do you love pizza too? You can celebrate on National Cheese Pizza Day on September 5!
