• In large bowl, toss onion, pepper, mushrooms, 2 tablespoons of the vegetable oil and 1 tablespoon of the steak seasoning; mix until evenly coated. Transfer vegetable mixture to sheet pan in single layer, allowing room for steak. In same bowl, add remaining 2 tablespoons oil and remaining 1 tablespoon steak seasoning. Add steak; rub mixture into steak. Transfer steak to pan with vegetables.
  • Broil 9 to 11 minutes, stirring vegetables once, until instant-read thermometer inserted in thickest part of steak reads 135°F (for medium). Transfer steak to cutting board; cover with foil, and let stand 5 minutes. Stir vegetables, and return to oven 3 to 4 minutes or until vegetables are tender.
  • Thinly slice steak into strips on the bias, against the grain. Cut longer strips in half. Return to pan with vegetables, mixing to combine. Top with shredded cheese; return to oven 1 to 2 minutes or until cheese is melted.
