sear the chicken on both sides with a sprinkle of salt. add uncooked pasta, salt, marinara, and water to the pot. stir very well, then cover the pot and let simmer, stirring every 5 minutes or so. after 15 minutes, add the mozzarella cubes and broil until bubbly and brown. YUM.
stir a few times to prevent sticking on the bottom. you can skip the oven if you want, just stir the mozzarella in right at the end until it's melty!
