Combine 2 cups cooked, cubed chicken, 6 1/2 cups water, 2 cups + 2 tablespoons milk, and 1/4 cup margarine in a large saucepan or kettle. Heat slowly until margarine melts, but DO NOT BOIL. Slowly stir in entire bag of soup mix. Reduce heat to low and simmer approx. 30 - 40 minutes, stirring occasionally. Optional: Serve over a fresh baked biscuit. (Great leftovers idea too! -- aka 'Chicken Ala King'!) May also crockpot on LOW 3 -4 hours.
