Philly Cheesesteak Stuffed Peppers

Who doesn't LOVE a good Philly Cheesesteak?  This type of recipe is totally up my alley, I'm not much a of a bread eater, so those same great flavors, minus the bread is a winner for me.  

Ingredients

8 oz. Thinly Sliced Roast Beef ( lunch meat works fine, leftover steaks do as well )

8 Slices Provolone Cheese or 8 oz. shredded mozzarella ( or any combination thereof )

2 Large Green, Red or Yellow Bell Peppers

1 Medium Sweet Onion – Sliced

8 oz. Baby Bella Mushrooms – Sliced

2 Tbs. Olive Oil

1 Tbs. Garlic – Minced

Salt and Pepper – to taste

Instructions

1. Preheat oven to 375 degrees.
2. Wash peppers and cut in half lengthwise, remove ribs and seeds. 
3. Heat butter, garlic, onions and  mushrooms in a large skillet, saute 8 - 10 minutes until onions become translucent. 
4. While onion and mushroom mixture is cooking, prep the peppers.  I poke holes in them and pre-cook for about five minutes.  It avoids underdone peppers as well all of their water ending up in your stuffing mixture.  I then fill them with cheese and cook for another 3 - 5 minutes, just until the cheese melts.
5. Slice the roast beef into strips and add to pan. Cook another 2-3 minutes or until hot (assuming the meat is pre-cooked... if not, cook meat first until done).
6. Spoon the meat/onion/mushroom mixture evenly into the bell peppers. Top each pepper with the remaining cheese and bake for at least 10 minutes ( at this point everything is already cooked ) until the top layer of cheese is melted to your level of doneness.
7. ENJOY!!!!
