Place all ingredients except noodles into the slow cooker and give it a stir. Cover and cook on high 4-5 hours or low 7-8 hours.
About an hour before you are ready to eat, remove the chicken and add the noodles to the slow cooker. Chop or shred the chicken and move it back to the slow cooker. Cover and cook till the noodles are tender (about 20-30 min). Make sure to keep an eye on the noodles so they do not become overcooked and mushy. Season with additional salt and pepper if desired.
