Directions

1. Rub both sides of steak with basil and Worcestershire-pepper. Place steak in a large resealable plastic bag or a shallow dish.
2. In a small bowl combine vinegar and sugar; pour evenly over steak. Seal bag; turn to coat. Refrigerate at least 6 hours.
3. Preheat broiler. Remove steak from marinade; pour marinade into a medium bowl. Place steak on broiler rack set in broiler pan. Season with freshly ground black pepper to taste.
4. Stir oil into marinade. Add bell peppers and onion; toss to coat. Place peppers and onion around steak. Spoon remaining marinade over steak and vegetables.
5. Place under broiler; broil 7 to 10 minutes per side or to desired doneness (145°F for medium-rare). If vegetables brown too quickly, remove and keep warm while steak continues to broil. Remove steak from broiler and let stand 3 to 5 minutes. Thinly slice steak against the grain, and serve with vegetables.
