Chop all vegetables medium-chunky (with a food processor, for ease)
Add all ingredients, including Soup Mix packet, but excluding matzo ball mix, to large pot. Bring to a slow boil and cook til breasts are cooked through (about 20 minutes). remove chicken.
Continue to cook soup until vegetables are tender. Remove to blender and puree. You can add a few shredded pieces of chicken to the blender as well.
Return puree to pot with about half of the chicken, shredded, reserving the rest for another project.
Add matzo balls. Cook them in the soup for about 20 minutes.
