Bravo for a tuna noodle casserole that forgoes crackers in favor of healthier ingredients like peas! This one is easy to prepare and relatively inexpensive. The flavor can be zipped up, if you desire, by sprinkling with Cheddar or Parmesan cheese the last 1/2 hour of cooking time, or after it is cooked. White albacore tuna tastes the best; however, other tuna works well too and is freer of Mercury. This recipe fits a 2.5 qt. crock pot.
