Caribbean Barbecued Pork Steaks

1 1/2-pounds boneless pork steak, about 1/2-inch
1 large red onion, sliced
3/4 cup fresh lime juice
1 teaspoon salt
1/2 teaspoon cayenne pepper

Place pork and onions in a glass 12x9-inch baking dish. Combine lime juice, salt and cayenne; pour over pork; cover and refrigerate for several hours. Lift pork steaks out of marinade, brushing off onions. Broil or cook over hot coals, 3 inches from heat, for 8 to 10 minutes, turning once. Heat onions and lime juice to boiling, about 5 minutes. Serve onions with cooked pork. Serve with tortillas, if desired.

Serves 6.
