4. Melt the Cheese: Place the cheese slices on top of the chicken and vegetable mixture. Cover the skillet and allow the cheese to melt for about 2-3 minutes.
5. Assemble the Sandwiches: Spoon the chicken and vegetable mixture onto the hoagie rolls. Add any optional toppings if desired, and serve warm.
