Season the chicken with salt, black pepper and Italian seasoning and heat the olive oil in a large skillet over medium-high heat.
Cook the cutlets for 3 to 4 minutes per side, until browned and 165°F inside, then rest them for 3 minutes.
Place the split rolls on a sheet pan and fill each with 1 chicken cutlet and 1/4 cup marinara.
Top each sandwich with 2 mozzarella slices and one-fourth of the Parmesan.
Broil the open sandwiches for 2 to 3 minutes, until the rolls toast and the cheese bubbles, then close them.
