Tortilla chips are made by cutting yellow, white, blue or red corn tortillas into triangular wedges and baking or frying them until crisp.

They are considered Mexican snack food, although they were popularized in Los Angeles in the middle of the 20th century -- first conceived as a way to use up irregular tortillas from a tortilla factory before they began being produced as a popular snack food in their own right.

Tortilla chips are eaten before a meal with salsa and/or guacamole. Tortilla chips are the base for chilaquiles and nachos, that Tex-Mex staple in which are baked tortilla chips smothered with cheese and loaded with toppings like beans, meat, sour cream, guacamole and salsa.
