Mustard-Molasses Flank Steak

Ingredients

• 1/3 cup balsamic vinegar
• 1/4 cup fat-free, less-sodium beef broth
• 2 tablespoons molasses
• 2 tablespoons whole-grain Dijon mustard
• 1/4 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 1 (1-pound) flank steak, trimmed
• Cooking spray
• Chopped green onions (optional)

Preparation

1. 1. Combine first 7 ingredients in a large zip-top plastic bag; seal. Marinate in refrigerator 30 minutes.
2. 2. Preheat broiler.
3. 3. Remove steak from bag, reserving marinade. Place steak on a broiler pan coated with cooking spray; broil 5 minutes on each side or until desired degree of doneness. Remove steak from oven; loosely cover with foil.
4. 4. While steak broils, place reserved marinade in a small nonstick skillet. Bring to a boil; cook until reduced to 1/3 cup (about 6 minutes), stirring occasionally.
5. 5. Cut steak diagonally across the grain into 1/4-inch-thick slices. Drizzle mustard-molasses sauce over steak. Top with onions, if desired.
