The Great American Food?

So I was making a PB&J sandwich for lunch in the kitchen at work yesterday and a co-worker posed an interesting thought. He said" you know most people say that hot dogs are the great American food, but I kinda think PB&J is." I got to thinking about it and I guess it could be considered that. I mean, when you were a kid your mom always had "staples" in the house. Those go-to snacks and dinners that if nothing else sounded good you could make on the quick. Hot dogs is usually one of these, but come to think of it mom always had PB&J in the house too. What do you think?
