This Shanghai-style chicken congee is a comforting and nourishing dish that can be made using a food processor. The chicken is cooked until tender and then shredded using the food processor. The shredded chicken is then added to a pot of rice porridge along with ginger, garlic, and green onions. Simmer until the rice is cooked and the congee has thickened. Serve hot with toppings like fried shallots, soy sauce, and cilantro.
