Recreate street tacos right at home with our Hand Made Style Street Taco Size tortillas. This recipe uses a simple, spicy rub instead of a more traditional (and labor-intensive) marinade. The salt and brown sugar help tenderize the skirt steak, which is a tasty, fast-cooking cut. You can substitute flank steak. Mexican markets also often sell marinated carne asada, which you can use here and skip the dry rub.
