Creating these incredible Philly Cheesesteak Bowls is easy when you follow these straightforward steps:

1. Heat the Oil: In a large skillet, heat the olive oil over medium heat.
2. Sauté the Vegetables: Add the sliced onion and bell pepper to the skillet. Sauté until they are soft and slightly caramelized, which should take about 5-7 minutes.
3. Cook the Beef: Push the vegetables to one side of the skillet. Add the thinly sliced beef to the empty side and season with salt and pepper. Cook for about 3-5 minutes until the beef is browned and cooked through.
4. Combine Ingredients: Stir the cooked vegetables and beef together in the skillet until well combined.
5. Melt the Cheese: Layer the sliced or shredded provolone cheese over the beef and vegetable mixture. Cover the skillet with a lid and let it sit for 2-3 minutes or until the cheese is melted.
6. Serve: Spoon the cheesy beef and vegetables into bowls and garnish with fresh chopped parsley.

This simple yet delightful process will lead you to satisfying Philly Cheesesteak Bowls that are bursting with flavor!
