Step 1

In a bowl, combine the ingredients for the chicken parm patties and mix well, forming 6 equal rectangular-shaped patties.

Step 2

Set up a breading station with one bowl containing egg and buttermilk, and another with Parmesan and panko. Bread the patties by coating them in egg mixture followed by the panko mixture.

Step 3

Preheat your griddle to approximately 350 degrees and add the frying oil.

Step 4

Cook the chicken patties for 2-3 minutes on each side.

Step 5

Place an aluminum pan on the griddle and add the marinara sauce.

Step 6

Once the chicken patties reach an internal temperature of about 165 degrees, toast the sub rolls on the cut side.

Step 7

Build the sandwich by placing ¼ cup of marinara on each chicken patty, followed by slices of mozzarella cheese. Cover with a dome for 1 minute, then remove and assemble the chicken on the rolls. Top with additional marinara.
