Creating these scrumptious Philly Cheesesteak Bowls is simple and straightforward. Follow these easy steps:

1. Cook the Rice/Quinoa: Begin by cooking your rice or quinoa according to the package instructions.
2. Sauté the Beef: In a large skillet, heat the olive oil over medium-high heat. Add the thinly sliced beef and season with salt and pepper. Cook it until browned, about 4-5 minutes.
3. Add Vegetables: Stir in the sliced onion, bell pepper, and mushrooms (if using). Cook until the vegetables have softened, about 5-7 minutes.
4. Add Worcestershire Sauce: Drizzle the Worcestershire sauce over the beef and vegetables, stirring to combine. Allow it to cook for an additional 2 minutes to absorb the flavors.
5. Melt the Cheese: Reduce the heat to low and sprinkle the shredded provolone cheese on top of the beef and vegetable mixture. Cover the skillet with a lid and let it sit for a couple of minutes until the cheese is melted and bubbly.
6. Assemble the Bowls: In serving bowls, layer the cooked rice or quinoa at the bottom. Then, spoon the cheesy beef and vegetable mixture on top.
7. Garnish (Optional): You can add toppings such as fresh parsley, sliced jalapeños, or a drizzle of hot sauce for added kick.

By following these steps, you’ll create an amazing Philly Cheesesteak Bowl that is sure to delight everyone!
