Instructions:

1.Prepare the Steak: Season the sliced ribeye with salt and pepper. Set aside.

2.Sauté the Vegetables: In a large skillet over medium heat, add 1 tbsp olive oil. Add the green bell pepper, onion, and mushrooms (if using). Sauté for about 5-7 minutes, or until the vegetables are soft and slightly caramelized. Remove from the skillet and set aside.

3.Cook the Steak: In the same skillet, add the remaining 1 tbsp of olive oil. Add the sliced ribeye and cook, stirring occasionally, for 4-5 minutes until browned and cooked through.

4.Combine Steak and Veggies: Return the sautéed vegetables to the skillet with the steak, mixing everything together. Reduce heat to low.

5.Add the Cheese: Lay the slices of provolone (or drizzle Cheez Whiz) over the steak and veggie mixture. Cover the skillet for 1-2 minutes, until the cheese melts.

6.Assemble the Sandwiches: Slice open the hoagie rolls, and fill each roll with the cheesy steak and vegetable mixture.

7.Serve: Serve hot, and enjoy your homemade Philly Cheesesteak!

This classic sandwich is hearty, cheesy, and bursting with flavor! Perfect for a cozy night in.
