1/4 cup parmesan cheese
1 egg
1/2 cup milk
1 tablespoon butter
2 tablespoons olive oil
more parmesan cheese, for sprinkling on top

Pound the chicken breasts between two slices of plastic wrap until about 1/4″ thick.
Season with salt and pepper.
Dredge chicken in flour and shake off excess.
Dip in egg/milk mixture, then in breadcrumb/Parmesan mixture.
Heat the butter and olive oil in a large deep skillet.
Brown the chicken breasts over medium heat until golden on each side (about 2-3 min per side).
Remove to a plate and keep warm.
Add the marinara sauce to the skillet.
Heat to boiling and simmer 10 minutes.
Add the chicken breasts to the sauce and sprinkle Parmesan over them.
Place a slice of mozzarella on each piece of chicken.
