Ingredient Substitutions: If you don’t have hoagie rolls, any soft sandwich bread can work as an alternative. Also, feel free to swap out the cheddar for your favorite cheese, such as Monterey Jack or pepper jack for a bit of heat. Optional Variations: For added flavor, try adding sliced jalapeños or a sprinkle of cayenne pepper to the chicken while grilling. You can also experiment with different sauces such as BBQ or blue cheese dressing. Storage Tips: These sandwiches are best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat in the oven to maintain a crispy texture.
