In a small bowl, mix together the Worcestershire sauce, olive oil, garlic powder, onion powder, salt, pepper, and Italian seasoning.
In a large bowl, combine the ribeye steak slices, bell peppers, onions, and mushrooms. Add the seasoning mixture and stir to coat.
Place the meat and veggies on a large sheet pan and spread out in an even layer. Bake for 15 minutes.
Remove from the oven and sprinkle with shredded provolone cheese. Return to oven and bake for another 1-2 minutes, or until cheese is melted.
Slice the hoagie rolls and spread butter on the inside. Place under the broiler for 1-2 minutes, or until lightly toasted.
Fill the rolls with the cheesesteak mixture and garnish with parsley if desired. Makes 4 hearty sandwiches.
Notes
Storage: Store the Philly Cheesesteak mixture separately from the rolls in an airtight container in the refrigerator for up to 3 days. To freeze this meal without the buns, place in an airtight freezer container or freezer bag and place in the freezer for up to 3 months. The texture may be altered after freezing. To thaw: place in the refrigerator to thaw overnight and reheat gently in the microwave or in a skillet on the stovetop, or on a sheet pan and place in the oven. Once heated through, assemble the sandwiches by filling the toasted hoagie roll.
