Chicken Parmesan Casserole

• 4 boneless chicken breasts (about 2.5 pounds), cubed and fully cooked
• 1 to 1.5 jars of marinara sauce
• ½ cup shredded or grated Parmesan cheese
• 1 pound fresh mozzarella cheese, sliced as thin as possible
• 2 cups panko or whole wheat bread crumbs
• 3-4 tablespoons olive oil
• Fresh, chopped herbs (I use basil...about 1/4 cup or so) 
• salt and pepper, to taste

1. Preheat oven to 350 degrees.
2. Grease an 9X13 casserole dish with cooking spray.
3. Layer the chicken in the bottom. Dump in the marinara sauce and mix with the chicken. Next, top with both cheeses until all the chicken is covered.
4. In a small bowl, mix the breadcrumbs, olive oil, fresh herbs and a dash of salt and pepper together.
5. Sprinkle the seasoned breadcrumbs over the top.
6. Bake for about 45 minutes or until golden on top and bubbling on the sides.
