1. In large pot, bring chicken broth, soup, bouillon, and water to a boil. Add chicken, vegetables, salt and pepper to taste, keeping in mind that dumplings will "soak up" some of the salt, and return to a boil for 10 minutes.
2. Meanwhile, make drop biscuits by combining baking mix and milk to a soft dough.
3. Drop dough into boiling soup by tablespoonfuls. Cover and reduce heat to medium-low, cooking for 10 minutes or until dumplings are fluffy when opened with a fork.
