Skirt steak is a juicy, flavorful cut of beef that doesn't need too much fuss, and this grilled skirt steak recipe is perfect for a busy weeknight since the seasonings are simple and preparation and cooking time is quick. A mixture of soy sauce, garlic, and cayenne pepper make up the marinade, and a nice dose of salt and pepper is added before the meat hits the grill. Skirt steak is a flat, long piece of meat, that although filled with connective tissue and therefore a bit tough, takes on a marinade nicely, with the meat's loose structure allowing for good absorption of flavors. Because it is a tougher, thinner cut of meat, skirt steak benefits from a short cooking time over high heat.
