*Heat 8-10 cups of chicken stock in a large saucepan. Bring to a simmer. Add chopped onion (1 whole onion), cubed potatoes (4-5 medium sized), sliced carrots (3-4 medium), and boil until tender (about 15 minutes). Add store bought frozen noodles (I use Grandmas Homemade Noodles found in the freezer section - I thaw them for 2-3 minutes in the microwave before adding them). Add shredded chicken (I use 1-2 cups shredded rotisserie chicken from Sam's Club). Boil 10-15 minutes more.
