Sizzling Philly Cheese Steak Skillet

In a large skillet, melt the butter over medium heat. Add the chopped red and green bell peppers, onion, and sliced mushrooms. Sauté the vegetables until tender.

Transfer the cooked vegetables to a bowl to keep warm.

In the same skillet, increase the heat to medium-high and add the thinly-sliced beef. Season with salt and black pepper. Cook until the beef is browned and cooked through.

Add the cooked vegetables back to the skillet and mix together with the beef.

Evenly distribute the shredded provolone cheese on top of the beef and vegetable mixture. Cover the skillet for a minute, or until the cheese is melted and bubbly.

Serve the Sizzling Philly Cheese Steak Skillet hot with your choice of side dish, or even spoon the mixture into hoagie rolls for a traditional sandwich-style serving!
