From the Jan/Feb 2009 magazine. I haven't tried this yet, but the pic looks sooo good I will have to soon!

• Serves: 4

Ingredients

• 1  cup barbecue sauce
• 1⁄4 cup fresh lemon juice
• 1  tablespoon prepared mustard
• 1 1⁄2 teaspoons celery seeds
• 1⁄4 teaspoon  hot sauce
• 2  garlic cloves, minced
• 1 (1 lb)  flank steak, trimmed

Directions

1. Preheat broiler.
2. Combine first 6 ingredients in a large bowl; add steak, turning to coat. Remove steak from sauce, reserving sauce mixture. Place steak on a broiler pan coated with cooking spray; broil 6 minutes on each side or until desired degree of doneness. Let stand 5 minutes. Cut steak diagonally across grain into thin slices.
3. While steak stands, bring sauce mixture to a boil in a saucepan over high heat. Reduce heat, and cook 5 minutes. Serve with steak.
