Enchiladas are an iconic food in Mexico and other South American countries. According to Gourmet Sleuth, recipes for enchiladas date all the way back to the Aztecs, though this was before the term 'enchilada' was used. The Aztecs would wrap meat up in a tortilla and pour some sort of salsa on top. And the rest, as they say, is history.
