Follow these simple steps to create your delicious Chicken Cheese Steak Sandwiches:

1. Prepare the Chicken: Slice the chicken breasts into thin strips for even cooking.
2. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Cook the Chicken: Add the sliced chicken to the skillet and season with garlic powder, paprika, salt, and pepper. Cook for about 5-7 minutes until the chicken is no longer pink and cooked through.

5. Melt the Cheese: Place a slice of cheese on top of the chicken and vegetable mixture. Cover the skillet with a lid and let it cook for 2-3 minutes until the cheese is melted.
6. Prepare the Rolls: While the cheese is melting, slice the hoagie rolls in half lengthwise.
7. Assemble the Sandwiches: Spoon the chicken and cheese mixture into each hoagie roll. Add any optional toppings you desire.
8. Serve: Enjoy your Chicken Cheese Steak Sandwiches warm, either as is or with your favorite sides.
