Directions:
Spray a large crock pot with a non-stick cooking spray or use a crock pot liner.
Place onion first and then add the chicken breasts.
Sprinkle both packets over the chicken.
Add pepperoncini, place pads of butter randomly on top, and then pour the juice over the chicken.
Cover and cook on high for 4-5 or low for 6-7 hours.
I await your comments! Enjoy!
