1 pound beef flank steak or top round steak -- to 1 1/2

1/2 cup cooking oil

2 tablespoons vinegar or lemon juice

1 clove garlic -- minced

Prepare and marinate steak by scoring meat and making shallow cuts at 1 inch intervals diagonally across the steak in a diamond pattern. Repeat on second side. Place meat in a plastic bag and set into a shallow dish. For marinade, combine oil, vinegar, garlic, 1/4 teaspoon salt and 1/4 teaspoon pepper. Pour over meat. Seal bag. Marinate at room temperature up to 1 hour or in refrigerator up to 24 hours; turn bag occasionally. Grill marinated steak on an uncovered grill directly over medium coals for 6 minutes. Turn and grill to desired doneness allowing 5 to 6 minutes more for rare or 7 to 8 minutes more for medium rare. Continue as above.
