Quick and simple, these hearty oven cheesesteak hot dogs are finished in the oven - with melted cheese, fresh seasoned steak, vegetables and a toasty bun.
Preheat oven to 350°. Line 9 x 13 baking pan with foil.
Separate and open buns. Lightly spread inside of buns with mayonnaise and mustard. Place a hot dog inside each bun. Pack hot dogs into prepared pan to fit.
Heat vegetable oil over medium-high heat in large skillet. Add steak, onions, salt, pepper, garlic powder and worcestershire sauce. Toss and cook until steak is done and onions are tender, about 5 minutes.
Spoon steak mix over hot dogs, dividing evenly. Lay cheese slice on top of each steak portion. Sprinkle with diced peppers.
Cover pan with foil. Place pan on center rack of oven and bake 40 - 45 minutes, until cheese is melted and hotdogs are steaming. Serve hot.
