Preheat oven to 375°F
Prepare your favorite tomato sauce
If necessary, take your full sized chicken breast and cut them in half to make them thin, as if they are being butterflied.
Place chicken between two sheets of plastic wrap. With the flat side of a meat tenderizer, flatten chicken so that the thickness is unformed thoughout. Be careful not to split breast into pieces.
Salt and pepper the chicken breasts.
Place whisked egg in one bowl.
Mix panko crumbs and freshly shredded parmesan in one bowl.
Dip chicken breast in egg, then in bread crumb mixture. Cover completely.
In a large saute pan, heat olive oil.
Saute breaded chicken for about 3 minutes per side. Breasts should be thin so this should be plenty of time to cook throughout.
Transfer chicken to baking sheet. Pour tomato sauce over chicken. Top with shredded mozzarella or sliced fresh mozzarella.
Place in over for about 5 minutes, or until cheese is melted.
Remove from oven. Serve with a side of your favorite pasta and enjoy!
