A fajita is a soft wrap filled with strips of sizzling meat, sliced peppers and onions, accompanied with cheese and toppings like salsa, guacamole or sour cream. Traditionally, the word “fajita” referred to the cut of steak used, as the Spanish word “faja” translates to “belt”. Nowadays, fajitas can include a variety of fillings, from chicken to fish and veggie options.
