Preparation:

In a small nonmetal bowl, combine steak sauce and lime juice. Use 1/4 cup steak sauce mixture to marinate steak for about 1 hour in refrigerator. Reserve remaining steak sauce mixture. Place onions and peppers in a foil grill pan (11-3/4x8-1/2x1-1/4 inches). Toss with 1/4 cup steak sauce mixture, oil and black pepper. Cover with second foil grill pan to form packet. Place on grill over medium heat; cook 15 to 18 minutes or until vegetables are tender. Meanwhile, remove steak from marinade; discard marinade. Grill steak over medium-high heat alongside vegetable packet 8 to 10 minutes per side or until done as desired. Thinly slice steak; add to vegetable mixture. Add remaining steak sauce mixture, tossing to coat well. Serve warm with flour tortillas. Note: To make grill pan packet, invert one grill pan over filled grill pan, overlapping slightly. Fold top of one short end down to seal; fold bottom of other end to seal.
