Place the chicken, soup, broth, water with corn starch mixed in,onion, zucchini, and carrot along with seasonings in a slow cooker.
Cover, and cook for 5 to 6 hours on High. About an hour before serving, add the peas and corn and place the torn biscuit dough in the slow cooker. Cook until the dough is no longer raw in the center.(or if you don't care for the dumplings, cook the biscuits and serve them on the side. I made mine with bisquick - just follow the package directions).
