Nachos are a Tex-Mex dish from northern Mexico. The dish is composed of tortilla chips (totopos) covered with cheese or cheese-based sauce, and is often served as a snack. More elaborate versions add more ingredients and can be served as a main dish. First created circa 1943 by Ignacio "Nacho" Anaya, the original nachos consisted of fried corn tortillas covered with melted cheddar cheese and sliced jalapeño peppers.
