Michael's Famous Philly Cheese Steak Sandwich

Tightly roll the eye round steak into a torpedo or log shape. Wrap tightly in plastic. Place log in freezer for 45 minutes to firm the beef into a tight but not frozen texture. Remove plastic, and working quickly, use an electric knife to slice the beef into paper-thin strips, almost shaving the beef. If this does not work well, use a sharp knife and cut the beef into the thinnest slices possible, then flatten the slices using a meat tenderizer. Refrigerate slices until ready to cook. Peel and halve onion. Slice into paper-thin half moon pieces. Halve the peppers, remove and discard seeds, and then slice into thick wedges. Warm 2 tablespoons of the oil in a large skillet over low heat. Add onions and cook 8 to 10 minutes, until caramelized and softened, stirring frequently. Do not allow them to brown. Transfer onions to bowl; add pepper to same skillet, still over low heat. Cook peppers 10 to 15 minutes, until soft and tender, flipping often. Transfer to bowl with onions. Season onion-pepper mixture to taste. Cover bowl to keep warm. In a clean skillet, warm the remaining 2 tablespoons oil over medium heat. Cook the beef in 2 batches, until lightly browned and cooked through, stirring often. Add olive oil if necessary. To serve: Pile beef strips, peppers and onions and cheese slices inside a hero roll.
