Best Chicken Parmesan Sandwich Recipe

Preheat your oven to broil.
Add the flour, one tablespoon of Italian seasoning, salt, pepper, garlic powder, and onion powder to a pie plate or shallow dish. Mix until combined. In another shallow dish, add the eggs, and in a third shallow bowl, add the panko.
Pat the breasts dry with a paper towel, then dredge them in the flour mixture, shaking off any excess flour, then the egg, and finally the panko. Set aside.
Add the oil and butter to a large skillet over low to medium heat. Once the oil and butter are hot, add the chicken.
Fry the chicken for 3-4 minutes. Flip each piece over and cook for 3-4 minutes, or until its internal temperature reaches 165°F, as measured by an instant-read meat thermometer. The time depends on the thickness of the breasts.
While the chicken is frying, split the rolls, place them on a baking sheet, and broil in the oven for 1 to 2 minutes until slightly toasted. Remove from the oven. Heat the marinara sauce in a small saucepan or the microwave.
Remove the skillet with the breasts from the heat. Spread about a quarter of a cup of marinara sauce on each piece, top with parsley, and then add about a quarter cup of mozzarella cheese on each and the remainder of the Italian seasoning.
Place the skillet under the broiler and broil for one to three minutes or until the cheese is melted and bubbly.
Spread about a tablespoon of marinara sauce on the bottom roll and add a chicken breast.
Add the top roll and optional basil, if desired, and serve immediately.
