Spiralize the zucchini to make noodles, give a rough chop, and set aside.
In a large stew/soup pot, add the chicken stock and the water. Heat to boiling.
Add the chicken breast and the carrots and reduce heat to medium/low. Simmer for 20 minutes.
After 20 minutes are up, check to ensure chicken is cooked through, then remove from the pot and shred. Return to the pot, add the zucchini noodles, and cook for 5-7 minutes.
