Philly Cheesesteak Stuffed Bell Peppers

Preheat your oven to 375°F (190°C).

Place the halved bell peppers in a baking dish, cut side up.

In a large skillet over medium heat, add the olive oil and sauté the onions and mushrooms until they are soft and the onions are translucent.

Add the thinly sliced beef to the skillet, season with garlic powder, salt, and pepper, and cook until the beef is browned.

Stir in the Worcestershire sauce and let it simmer for a couple of minutes to blend the flavors.

Fill each bell pepper half with the beef mixture, packing it in tightly.

Top each stuffed pepper with a slice of provolone cheese.

Cover the baking dish with foil and bake in the preheated oven for 20 minutes.

Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.

Let cool slightly before serving.
