This question is for North Americans!

This is directed to Caucasian people, but how come when food like chinese/italian/indian etc is called ethnic food, but food like burgers, fries, hotdogs, are not called ethnic (at least I have never heard them referred to that), when Caucasian is an ethnicity.

I guess I shouldn't have said caucasian is an ethnicity, but why are people saying there are different races?
