Season chicken with salt and pepper on both sides.
Dip the chicken breast in egg mixture and dredge in the crumbs pressing lightly until coated.
Heat olive oil in a large non stick skillet until hot and cook chicken breast on each side, 2 to 3 minutes or until golden brown. Repeat with remaining chicken.
Transfer chicken to a baking dish in a single layer. Top each one with some of the tomato sauce and a few slices of the mozzarella cheese. Sprinkle on the remaining parmesan cheese.
Bake for 15 to 20 minutes until the chicken is cooked through and the cheese is melted.
