Put thawed chicken breast side down in crockpot. Add enough water to cover the bottom of the crockpot. Sprinkle edamame still in the pods over the chicken.
Cover the crockpot. Cook on low for 8-9 hours.
Remove chicken from crockpot. It may want to fall apart, so be careful and don't get burned. Cut chicken up into serving pieces.
Serve edamame alongside.
Notes
We added a carrot raisin salad (raisins and shredded carrots mixed with mayonnaise) and lettuce salad to complete this meal.
