[Kitchen Witch]

here's a recipe for you to try (if you'd like):

1/3 cup white vinegar
1/3 cup olive or vegetable oil
3 tablespoons packed brown sugar
3 tablespoons soy sauce
1/2 teaspoon coarsely ground pepper
2 medium onions -- sliced
1 clove garlic -- finely chopped
1 1/2 pound beef flank steak

Mix all ingredients except beef in shallow nonmetal dish or resealable plastic bag. Add beef, turning to coat with marinade. Cover dish or seal bag and refrigerate, turning beef occasionally, at least 8 hours but no longer than 24 hours.

Brush grill rack with vegetable oil. Heat coals or gas grill for direct heat.

Remove beef and onions from marinade; discard marinade. Place onions in 9-inch round aluminum foil pan. Grill beef uncovered 2 inches from MEDIUM heat about 12 minutes for medium-rare doneness, turning once. At same time, add pan of onions to grill, stirring occasionally, until tender.

Cut beef diagonally across grain into very thin slices. To serve, top with onions.
Makes 4 to 6 servings

remember - there really is no such thing as a "london broil" - it is a flank steak and london broil is just a cooking method for the steak - but the stores label them as london broil - ??????????????
