Prep: Place the roast at the bottom of the slow cooker, pour over the pepperoncini juice. Sprinkle the dry gravy packets on top of the roast. Add the pepperoncini peppers and butter over the top of the roast.
Cook: Cover and set the slow cooker to low for 6-8 hours or until fork tender.
Serve: Once cooked shred with a fork and mix the meat back in with the juices from the slow cooker. Serve over mashed potatoes, rice or noodles.
