Combine Italian dressing and water. Pour over chicken. Cook on LOW for 8 hours, or HIGH for 4 hours (until chicken is cooked through).
Remove chicken from the slow cooker and shred. Leave the liquid stock in the slow cooker.
Mix together soup and cream cheese. Pour cream cheese mixture into the slow cooker and mix with the chicken stock. Stir broccoli into the slow cooker mixture. Add chicken back to the slow cooker and mix well.
Turn the slow cooker on HIGH and cook until heated through (about 30 minutes).
Salt & pepper chicken breasts and place in the bottom of crock pot. Spoon soup over the chicken. Cut butter into several pats and place pieces evenly over soup.
Whisk the bouillon with the broth and pour over soup. Place lid on pot and turn to low. Cook for 6 hours.
Remove chicken and tear into pieces. Add back to pot. Now add noodles and if adding veggies add now. Cook for another 2 hours or until noodles are desired tenderness. Stir a few times during last 2 hours. You may want to add more broth to thin out at the end of cooking, as the home made noodles thicken the broth.
Sprinkle with parsley and mix in, if using at the end of cooking.
Salt & pepper if needed and Serve.
