Step 1: Prepare the Chicken

1. Place the chicken breasts in the freezer for 15 minutes (this makes slicing easier).
2. Slice the chicken into thin strips. Season with salt, black pepper, garlic powder, paprika, and onion powder.

Step 2: Sauté the Vegetables

1. Heat 1 tbsp olive oil in a skillet over medium heat.
2. Add sliced bell peppers, onions, and minced garlic. Sauté until softened and slightly caramelized (5-7 minutes).
3. Remove vegetables from the skillet and set aside.

Step 3: Cook the Chicken

1. In the same skillet, add 1 tbsp olive oil and butter.
2. Add the sliced chicken and cook until fully cooked and lightly browned (5-7 minutes).
3. Return the sautéed vegetables to the skillet and mix well.

Step 4: Melt the Cheese

1. Lower the heat and divide the chicken and veggie mixture into two portions in the pan.
2. Lay two slices of cheese over each portion. Cover the skillet with a lid and let the cheese melt (1-2 minutes).

Step 5: Toast the Hoagie Rolls

1. Spread butter on the inside of the hoagie rolls.
2. Toast on a skillet or in the oven at 375°F (190°C) for 3-4 minutes until golden brown.

Step 6: Assemble the Sandwich

1. Spread mayo (if using) inside the toasted hoagie rolls.
2. Use a spatula to scoop the cheesy chicken and veggie mixture into the rolls.
3. Serve hot with fries, coleslaw, or a fresh salad. Enjoy!
