1/4 cup soy sauce
3 tablespoons honey
2 tablespoons vinegar
1 1/2 teaspoons garlic powder
1 1/2 teaspoons ground ginger
3/4 cup salad oil
1 green onion, finely chopped
1 (1 1/2-pound) flank steak

Mix soy sauce, honey and vinegar; blend in garlic powder and ginger. Add oil and green onion. Place steak in small shallow pan; pour on enough honey mixture to cover. Let stand for at least 4 hours. Reserve any remaining mixture for basting.
Remove steak from pan and discard marinade. Grill steak over hot coals for 5 minutes on each side, basting occasionally with reserved honey mixture.
