First, slowly add in the water into the cream of chicken soup while mixing. Next, whisk in the packs of chicken gravy and pepper.
Now, add the chicken breast into the crockpot. Then, pour the mix you just made around them.
Cook the chicken on high for 4 hours or low for 6-8. The chicken is done when you can easily shred it but the time given tends to never fail.
Remove the chicken breast and shred the chicken. Now, add the chicken back into the crockpot with the gravy and serve.
