1 bunch cilantro, cleaned and stemmed
3 cloves garlic
1/2 small onion
1 tablespoon Worcestershire sauce
2 to 3 serrano chiles, optional
2 pounds "flat meat," inside skirt steak (the key is a thin steak, which good butchers can cut for you)

combine the cilantro, garlic, onion, Worcestershire, optional chiles and a teaspoon of salt, or to taste. Blend the ingredients to make the marinade, and rub the marinade all over the meat. Place the meat in a large, sealable plastic bag or in a large baking dish covered with plastic wrap, and refrigerate for at least 1 hour, up to several hours, to marinate.

heat a grill over medium-high heat until hot. Oil the grill then add the

. Serve hot.
