Put diced onion and chicken breasts evenly in the bottom of the crock pot
Sprinkle packets of ranch dressing and au jus mix on top of meat.
Then add in pepperoncini peppers and pepperoncini juice, and top mixture with the pats of butter spread evenly on top.
Cover and cook on High for about 5 hours or Low for 7-8 hrs.
Can serve chicken whole or shred with two forks. Then serve over mashed potatoes, rice, or noodles. ENJOY!
NOTE: For a fun twist, shred chicken, then scoop into a toasted hoagie roll, top with provolone cheese, and place under broiler in oven for a 1-2 minutes until cheese is melted. ENJOY!
