Place rotisserie chicken in a pot of water. Boil water adding carrot shavings and celery, a little onion and garlic for flavor. Strain chicken and place in fridge to cool.
I use prepared dumplings from Mary Hill.
After chicken is strained and in the frig. Bring water back up to a boil and add dumplings one at a time. Turn heat to low, cover and cook 30 minutes.
