In a large pot of water, boil uncooked pasta until fork tender, 11 – 13 minutes.

Preheat oven to 375 degrees F.

Spray a 3 quart baking dish with non-stick cooking spray and add the pasta to the bottom.

Add pasta sauce and tomatoes to pasta, stir.

Spread chicken chunks in an even layer over the pasta.

In a small bowl, mix panko crumbs and Parmesan cheese. Spread in an even layer over the chicken.

Bake uncovered for 40 minutes.

Spread mozzarella cheese over casserole and continue baking 10-20 minutes, until chicken is no longer pink and cheese is melted.
