½lbdeli roast beef, sliced thin and coarsely chopped
1cupshredded mozzarella or
8slicesprovolone cheese
Instructions
Cook the filling:
Heat a large skillet over medium-high heat. Once hot, add 1 tablespoon of oil and distribute it around the pan. Add the sliced mushrooms, sliced bell peppers, onions, and garlic, and continue to cook, stirring throughout, until the onions are translucent and the peppers are soft for about 5 to 7 minutes.
Once the veggies are tender, add the chopped deli roast beef to the pan. Stir to combine it with the veggies and cook it for about 2 minutes, until warm. Turn off the heat.
Assemble:
Cover the contents of the pan with the shredded mozzarella cheese or the sliced Provolone. Cover the pan with the lid for a minute, just long enough to melt the cheese.
While the veggies cook, warm the hoagie rolls in the oven at 350F for 7 to 10 minutes. Remove them from the oven, slice them in half, and stuff them with the Philly cheese steak mixture in the skillet.
