Preheat oven to 425 Fahrenheit. While oven is heating, on a shallow plate mix together the panko bread crumbs, parmesan cheese and italian seasoning.
If your chicken breasts are large, pound them out to be about 1/2 inch thick. Season with pepper. Cover chicken with pesto sauce on both sides.
Dip chicken in bread crumb mixture and flip to adhere the breading to both sides. Place on a prepared baking sheet.
Place in oven for 18-20 minutes
Remove from oven and top with pasta sauce then parmesan cheese.
Place back in oven for 5 minutes until cheese melts. (If you want it to be more brown and bubbly turn on the broiler and watch carefully as it will get there quickly!)
