Heat olive oil in a large skillet over medium-high heat.
Add the sliced chicken and season with salt and pepper. Cook for about 5-7 minutes, or until the chicken is cooked through and no longer pink. Remove the chicken from the skillet and set aside.
In the same skillet, add the sliced onion and bell peppers. Sauté for about 5-6 minutes, or until the vegetables are tender and slightly caramelized.
Add the minced garlic and Worcestershire sauce, stirring to combine, and cook for an additional 1-2 minutes.
Return the cooked chicken to the skillet and mix well with the vegetables. Allow everything to heat through for another 2-3 minutes.
Preheat your oven’s broiler. Split the hoagie rolls and place them on a baking sheet.
Evenly distribute the chicken and vegetable mixture into each roll, then top with a slice of provolone cheese.
Broil the sandwiches for 2-3 minutes, or until the cheese is melted and bubbly. Keep a close eye to prevent burning.
Remove from the oven, garnish with fresh parsley, and serve immediately.
Notes
You can substitute chicken thighs for chicken breasts for a juicier option.
Feel free to add other toppings like mushrooms or jalapeños for extra flavor.
Serve with a side of fries or a salad for a complete meal.
