Generously season your chicken breasts with black pepper and garlic powder.
In your crockpot, whisk together the water, cream of chicken soup and both packets of chicken gravy mix.
Add the seasoned chicken breasts and use a spoon to cover them well with the gravy mixture.
Cover and cook on LOW for 6-8 hours or until the chicken shreds easily.
Once cooked, use a couple of forks to shred the chicken into small pieces.
Stir in the sour cream and allow it to warm for an additional 15 minutes.
Serve over mashed potatoes, rice or pasta.
