1 lb boneless skinless chicken breasts
1/4 cup prepared pesto sauce (or more)
sliced tomatoes
1/2 cup mozzarella cheese shredded or sliced
grated parmesan if desired
Salt and pepper to taste

Preheat oven to 400. Line a baking sheet with foil or parchment paper, and mist with cooking spray. (I use nonstick tinfoil)
Butterfly or slice chicken breasts to create 4 thin cutlets. Season each piece with salt and pepper.
Spoon pesto sauce evenly onto each piece of chicken, and spread. Place in oven, and roast until chicken is cooked through, about 15-18 minutes.
Remove from oven, and top each piece of chicken evenly with tomatoes and mozzarella cheese. Sprinkle with some grated parmesan if desired. Return to oven and cook until cheese is melted, about 5 minutes.
