Grilled Flank Steak with Chimichurri Sauce

2 lb Flank steak

-----------------------------------SAUCE----------------------------------- 4 Jalapeno peppers, remove

-stems and seeds, chop fine 1/2 c Chopped onion

4 Cloves garlic, minced

1/4 c Chopped fresh parsley

1 ts Oregano

1 ts Fresh ground black pepper

1/2 c Olive oil

1/4 c Red wine vinegar

2 tb Lemon juice

1/4 c Water

Combine all ingredients for the Chimichuri Sauce. Score each side of the steak about 1/8 to 1/4" deep and rub in the sauce, reserving some of the sauce to serve with the meal. Place the meat and marinade in a ceramic or glass pan and marinate overnight in the refrigerator. Remove the meat and extra sauce from the refigerator and allow to sit at room temperature before grilling. Grill the meat over charcoal or under a broiler until medium-rare. Carve the steak immediately accross the grain into strips about 1/4" thick and serve with extra sauce. If the meat is allowed to sit before carving, it will toughen.
