Pizza may be a product of Old World Italy, but it's now as American as hot dogs and apple pie. Delivered or in a restaurant, thick crust or thin, plain cheese or loaded with toppings, it's the favorite we can't resist. Americans eat 350 slices every second – or 100 acres of pizza every day. Over the course of a year, that's enough pizza to cover every inch of Manhattan. Twice.
