Philly Cheesesteak Stuffed in a Portobello Mushroom

 

6 oz sirloin steaks thin sliced

1/8 tsp. salt

pepper

3/4 cup onion diced

3/4 cup green pepper diced

1/4 cup sour cream light

2 T. mayonnaise light

2 oz cream cheese light, softened

3 oz provolone cheese shredded

4 medium Portobello mushrooms with no cracks

 

Preheat the oven to 400F. Spray a baking sheet with oil. Gently remove the stems, scoop out the gills and spray the tops of the mushrooms with oil, season with 1/8 tsp. salt and fresh pepper. Season steak with salt and pepper on both sides. Spray a large skillet with cooking spray and heat on high, let the pan get very hot then add the steak and cook on high heat about 1 to 1 1/2 minutes on each side, until cooked through. Transfer to a cutting board and slice thin, set aside. Reduce the heat to medium-low, spray with more oil and sauté onions and peppers 5 to 6 minutes, until soft. Combine all the ingredients in a medium bowl. Transfer to the mushroom caps, about 1/2 cup each. Bake in the oven until the cheese is melted and the mushrooms are tender, about 20 minutes.
