Nachos are a Mexican-American Tex Mex dish that was created by Ignacio "Nacho" Anaya in Piedras Negras, Mexico, for U.S. military wives in 1943.
Nachos were invented in Mexico, although the nachos also originated in a border town to suit the tastes of Americans.
The nachos are also often viewed as a borderland or Tex-Mex creation, instead of just traditional, pre-colonial Mexican cuisine.
