2 cups tomato paste
1 pkg chicken breast tenders (we cubed ours to make it easier for the kids)
2 cups Mozzarella cheese
8 oz uncooked spaghetti

Heat over to 350 degrees. Into a glass baking pan, spread 1 cup of tomato paste. Add in chicken and spoon remaining pasta sauce over the chicken. Sprinkle with cheese. Bake uncovered for 30 - 35 minutes or until mixture is bubbly and chicken is pink in the center. While that is cooking, make spaghetti like you normally do. Serve chicken and sauce over the spaghetti.
