This recipe calls for a gourmet mushroom mix, but most mushrooms will work.
1 (1-pound) flank steak, trimmed
1/2 teaspoon salt
1/2 teaspoon freshly ground black pepper
1/2 cup chopped shallots
1 (4-ounce) package gourmet mushroom mix
1/3 cup water
2 teaspoons Dijon mustard
1 tablespoon Worcestershire sauce
1/2 teaspoon chopped fresh thyme
1/4 cup fat-free sour cream
How to Make It
Sprinkle steak evenly with salt and pepper. Place steak on a broiler pan coated with cooking spray. Broil 6 minutes on each side or until desired degree of doneness; let stand 10 minutes.
Heat a large nonstick skillet over medium heat. Coat pan with cooking spray. Add shallots to pan; cook 3 minutes, stirring occasionally. Add mushrooms to pan. Cover and cook 4 minutes or until mushrooms are tender, stirring occasionally. Stir in 1/3 cup water, mustard, Worcestershire, and thyme. Cover and cook 2 minutes. Remove from heat; stir in sour cream.
Cut steak diagonally across grain into thin slices. Serve with mushroom sauce.
