Place chicken breast, soup, broth, water, salt, garlic powder, pepper, and onion in crockpot (everything except your biscuits)
Cover and Cook on low six to seven hours
One hour before dinner time, add quartered biscuits to crockpot. Gently stir in biscuits so that they're covered. (I used 1 and 1/2 of the two small cans of biscuits - enough to fill up to the top of my crockpot... you can use any leftover biscuits to bake and enjoy with your meal!)
Cover and Cook an additional hour on low
Enjoy!
