Trim excess fat from steak; score steak on both sides in 1 1/2 inch squares. Place steak in a large shallow dish or zip-top heavy-duty plastic bag. Combine oil and remaining ingredients, stirring well. Pour over steak. Cover or seal; marinate in refrigerator 8 hours, turning occasionally. Drain steak, reserving marinade. Grill, covered, over medium coals (300 to 400 degrees) 6 to 8 minutes on each side or to desired degree of doneness, basting twice with marinade. Discard remaining marinade. To serve, slice steak across the grain into thin slices. Yield: 6 servings. Note: Steak may be grilled ahead of time and served cold.
