The humble potato was domesticated in the South American Andes some 8,000 years ago and was only brought to Europe in the mid-1500s, from where it spread west and northwards, back to the Americas, and beyond.
Although originated in Mexico, chilies are today cultivated around the world, with Peru holding the highest cultivated capsicum diversity. Christopher Columbus encountered these chilies when he discovered America, calling them “peppers” because of the similar spicy taste like the familiar peppers in Europe.
Alternatively, a dish including squash, corn, beans, and bison meat would be quite "American."
weirdly, that kinda tracks. I think I recall that jerky was a native american thing first, although it seems to be kinda contested if you do google searching... Pemmican would certainly be and it's a close relation, at least.
