I love chicken Parmesan sandwiches, and I love chicken cordon bleu. So why not combine the two?
Step: 1
Slice each chicken breast down the center to make 4 cutlets. Place each between 2 pieces of plastic wrap and pound to about 1/2 inch thinness with a meat mallet.
Step: 2
Marinate chicken breasts in Italian dressing in the refrigerator overnight.
Step: 3
Remove chicken to bring to room temperature 1 hour before cooking.
Step: 4
Combine flour and baking powder in one bowl, milk and egg in another bowl, and bread crumbs in a third bowl. Set aside.
Step: 5
Heat 1 tablespoon butter in a pan over medium heat. Cook prosciutto in the hot butter until it starts to brown, about 5 minutes. Transfer to a paper towel-lined plate.
Step: 6
Bring marinara sauce to a simmer in a saucepan.
Step: 7
Heat oil in a deep-fryer or large saucepan to 375 degrees F (190 degrees C). Preheat the oven to 450 degrees F (230 degrees C).
Step: 8
Lay chicken cutlets out flat. Line 1/4 of mozzarella cheese down the center of each and sprinkle 1/4 of prosciutto over cheese. Fold cutlets in half over the stuffing and secure edges together with toothpicks.
Step: 9
Dunk rolled chicken into the flour mixture, then egg mixture, and finally bread crumbs.
Step: 10
Drop chicken into the preheated fryer and cook until crumbs are golden brown, chicken floats, and is no longer pink in the center, 6 to 7 minutes. Transfer to a paper towel-lined plate to let grease run off.
Step: 11
Cut sub rolls down the centers and spread remaining butter into interiors. Assemble sandwiches in the following manner: bottom sub half, chicken cutlet, marinara, provolone cheese, Parmesan cheese, and top sub half. Transfer subs to a baking pan.
Step: 12
Toast in the preheated oven until bread is crisp and cheeses are melted, about 2 minutes. Serve hot.
