Wash livers and slice into thin slices.
Cut kidneys in half, and cut lengthwise again. Remove the layer of fat and fibre, and slice. Cut cross petterns on kidney slices.
Bring congee to the boil again, then add in all the ingredients. Boil over high heat for 3-4minutes until ingredients are thoroughly cooked, then serve.
