The main ingredient in nachos is tortilla chips. Originating in Mexico, nachos typically consist of crispy, fried corn tortillas cut into triangular shapes. The dish is popular in various forms and often topped with melted cheese, jalapeños, salsa, guacamole, and other toppings, making it a beloved snack or appetizer. Nachos were first created in the 1940s by Ignacio "Nacho" Anaya, who prepared them for customers at a restaurant in Piedras Negras, Mexico. Since then, nachos have become a staple in American cuisine, particularly popular at sporting events, movie theaters, and casual dining establishments.
