I marinated a London broil steak with Worchester sauce, McCormick Montreal Steak seasoning, minced garlic, and minced onion, rubbed steak with olive oil and A-1 Steak sauce for 4 hours. I used white onion, green, red bell peppers and mushrooms sauteed in fry pan with steak seasoning in olive oil. I used provolone and pepper jack cheese. I cooked in vegetable oil but will try in the air fryer next time. My husband, my grandson and son-in-law said it was 5 stars!
