On the stove, put chicken, soup, and dressing mix in a saucepan. Stir together and mash up chicken pieces. Heat over medium, adding milk to thin (about 1/2 cup). Heat for 10 minutes or so, stirring occasionally. Serve over rice. We always eat this with peas and it's good mixed together if you don't mind mixing your food.
*Helpful hints: This is also good with Italian dressing mix. If you plan ahead, you can also make this in the crock-pot with frozen chicken breasts. If you like it really rich, you can add cream cheese.
