- 1 tablespoon olive oil
- 1 ½ pounds sirloin steak - thinly sliced into 1-inch pieces
- 2 tablespoon butter
- 1 red bell pepper - seeded and sliced
- 1 green bell pepper - seeded and sliced
- 1 white onion - thinly sliced
- 3 cloves garlic - minced

Instructions
- Preheat the oven to 375 Fahrenheit and spray a 9x9 or similarly sized casserole dish with non-stick cooking spray. Set aside for later.
- Heat the olive oil in a large skillet set over medium heat. Once the oil is hot, add the steak and cook until browned about 6-8 minutes. Drain any excess grease from the skillet.
- Add the butter, red pepper, green pepper, and onion and cook until softened, about 5 minutes. Stir in the garlic and cook for 30 seconds.
- Add the mushrooms and cook until softened, about 5 minutes, then stir in the hot sauce, Worcestershire sauce, salt, and pepper.
- Stir in the cream cheese until fully melted and incorporated with the steak and veggies. Move the pan off the heat and stir in the mozzarella until fully melted.
- Spoon the cheesy meat mixture into the prepared baking dish, then layer the slices of provolone cheese over the top. Bake in the oven for 20 minutes or until the top is golden and bubbly.
- Serve with freshly minced parsley for garnish if desired.
