Mix the soup with the milk. Put about half of the soup on the bottom.
Place Chicken breasts on top. Layer with the sliced ham and swiss cheese. (This is where I sliced the chicken in half and put the ham and cheese inside and put swiss cheese on the top).
Put the rest of the milk/soup mixture on the top of the swiss cheese. Then lastly, put the stuffing mix on the very top and drizzle it with the 1/4 cup butter. Cook on low for about 4-6 hours.
