Preheat oven to 375°. Spray 2 rimmed baking pans with cooking spray; rub steak with seasoning, and ½ teaspoon each salt and black pepper. Place steak on 1 prepared pan; spread peppers and onions on second prepared pan and spray with cooking spray. Bake steak and vegetables 12 minutes or until internal temperature of steak reaches 145° for medium-rare or to desired doneness, and peppers and onions are tender-crisp, turning steak and stirring vegetables once. Transfer steak to cutting board; tent loosely with foil and let stand 5 minutes.
On microwave-safe plate, stack wraps between 2 damp paper towels; heat in microwave oven 30 seconds or until warm. Very thinly slice steak across the grain; serve with wraps and cheese along with cilantro and limes, if desired.
