Tips:
If using a spaghetti pot on the stovetop, cover and cook on medium for the first half hour, stirring every 10-15 minutes. For the rest of the time, drop the temperature to low and simmer until carrots and celery are tender, stirring every 10-15 minutes.
If using a cooked chicken, chop the chicken into bite-sized pieces, drop into the pot and mix with the other ingredients. Cook on medium heat until veggies are tender, about 30 minutes, stirring every 10 minutes.
