Spread the flour on one plate, the breadcrumbs mixed with Italian seasoning on another, and the beaten eggs in a shallow dish.
Flatten each piece of chicken by pressing down on the thickest part or by laying the breast between two pieces of plastic wrap and pounding it with a meat tenderizer or a cooking pot.
Coat each piece of chicken with flour, dip in the beaten egg, and coat with the seasoned breadcrumbs.
Place the breaded chicken on a parchment paper-lined cookie sheet and place in the freezer for an hour or two.
Transfer the chicken to a large resealable freezer bag. Remove the excess air and seal.
Fill one quart-sized (medium) freezer bag with the mozzarella slices and place the red sauce in another quart-size bag. Staple the three bags together above the seal.
Freeze.
Thaw in the refrigerator overnight.
Place chicken in a single layer on a greased baking dish.
Bake uncovered at 375° for 20 minutes.
Pour the red sauce over the chicken and bake for another 10 minutes or until the internal temperature reaches 165°.
Place a slice of cheese on top of each piece of chicken and bake until melted.
Serve with pasta and additional red sauce.
