Cook your chicken however you like. Once cooked through, dice into bite-sized pieces and set aside.
Prepare your stuffing according to box directions.
Turn your crockpot on high. Cover the bottom of your crockpot with the stuffing mixture (stuffing is your bottom and top layers only).
Pour one can of green beans on top then add 1/3 of your cooked chicken on top of the green beans. Cover with one of your cans of cream soup. Start the process over by layering one can of green beans, then chicken, then one soup can until all ingredients are gone. Save the other half of your stuffing mixture for your very top layer.
Cover and cook on high until boiling (bubbling)
