Well, thing is... there aren't any. America has only been around for about 250 years, and it was formed by immigrants from all around the world. So American food is pretty much just the best food from around the world (that is to say, Italian, Asian, and Mexican). Of course, we have hamburgers, hotdogs, fried chicken (fried anything, really), and barbeque, but all of our good foods are from other places.
@sypkokr18 Like the previous comment said, we don’t really have any. Of course, hamburgers are popular. But, I would say we “Americanize” food by adding more fat or sugar to our food. For example, American pizza has a lot of cheese compared to Italian pizza. We love cheese in the USA!
