chicken breast cut or pounded into 1/2-inch thick slices
each salt and pepper
(10 ounces) frozen spinach, thawed and drained or 4 cups fresh spinach leaves
shredded mozzarella cheese
Preheat oven to 350 degrees F.
Pour ½ cup of the pasta sauce in a large baking dish. Sprinkle salt and pepper over chicken and add to the dish. Top with the remaining ½ cup of pasta sauce, spinach and mozzarella.
Bake for 30 to 40 minutes until chicken is no longer pink inside and cheese begins to turn brown. If you have a food thermometer, check in the thickest part of the chicken to be sure the temperature is at least 165 degrees F. If not, cover and return to heat.
