A fajita, in Tex-Mex cuisine, is any stripped grilled meat, optionally served with stripped peppers and onions usually served on a flour or corn tortilla. The term originally referred to skirt steak, the cut of beef first used in the dish. Popular alternatives to skirt steak include chicken and other cuts of beef, as well as vegetables instead of meat. In restaurants, the meat is usually cooked with onions and bell peppers. Popular condiments include shredded lettuce, sour cream, guacamole, salsa, pico de gallo, shredded cheese, refried beans, and diced tomatoes. "Tacos de arrachera" is applied to the northern Mexican variant of the dish.
