In a medium sauce pan, pour 1-32oz. pkg of the chicken broth (or use 4 cups of your own). Bring to a boil. Add the chicken breasts. Simmer for 6-8 minutes, then TURN OFF the heat and let chicken poach in broth for about 15 minutes.
Remove the chicken from the poaching broth (reserve broth). Let the chicken rest/cool on a plate for shredding later.
While the chicken is poaching, start slicing your vegetables! Then, in a large soup pot, heat oil over medium heat. Add onions, and saute until they start to soften. Add carrots, celery, zucchini, shallot & seasonings (to taste). Cook, stirring often, until the vegetables are nice and soft. Add the broth used to poach the chicken, remaining 2 packages of chicken broth (or 8 cups more of your own), wine and pasta.
