Which Italian food is the most popular in America?

Pizza is the most popular Italian food in the US. The pizza we buy, although delicious, is not at all like its Italian cousin. Both have crust, cheese, and tomato on them, but in Italy these ingredients are not broken down as much. You will see slices of tomato and cheese instead of cooked tomatoes or shredded cheese. The taste, too, is different; Italian pizza tastes much fresher.
