This classic comfort food is made even easier with the help of a food processor. Pulse together flour, baking powder, and salt to make the dumpling dough. In the Dutch oven, sauté onions, carrots, and celery until tender. Add chicken broth and shredded chicken, then drop spoonfuls of the dumpling dough on top. Cover and simmer until the dumplings are cooked through. Serve hot and enjoy!
