In slow cooker add chicken breast, water, chicken base, onion, celery, carrots, and potatoes, diced tomatoes with their juices, garlic, parsley, 2 teaspoons salt and pepper.Cook on high for 6 hours, remove chicken breast and shred, place back in soup and bake another 2 hours.At the end of 8 hours, use a potato masher, mash the soup around a few times, letting some of the potatoes get a little smashed. I don’t try too hard on this, I just mash 2-3 times and call it good. Add noodles to the slow cooker and season with additional salt and pepper if needed.Serve with ¼ cup of sharp cheese on top, we like Asiago and parmesan both.**We actually like to serve the serve the soup with the noodles on the side, letting each person add the amount of noodles they want.*
