The term 'Tex-Mex Staple' refers to three popular Mexican dishes: Chili (5 letters), Taco (4 letters), and Tortilla (8 letters). Chili is a stew-like dish made with meat, beans, and spices. Tacos are a type of Mexican sandwich made with a folded tortilla and filled with various ingredients such as beef, chicken, or vegetables. Tortillas are thin, round flatbreads made from corn or wheat flour. All three dishes are staples of Tex-Mex cuisine, which is a fusion of Mexican and American flavors.
