American Greek food as mentioned above is also a good example of food that has developed farther from the culture it came out of into a new form in America. Tex-mex is called TEX-mex for a reason, because if it didn't have Texan flair to it it wouldn't be tex-mex.
Actual chili, for instance, doesn't really exist outside of America, and that's because it was a combination of things that we had on hand in our country with cooking styles developed by Mexicans.
