Place sliced smoked sausage in the crockpot. Sprinkle the ranch seasoning mix and the gravy mix over the sausage. Then place the peppers and the butter in the slow cooker. Pour the pepperoncini juice over the top. Cook on low for 2-3 hours, stirring a couple of times.
Notes
If you don't want any heat or spice in this dish, do not add the juice. Just add a 1/4 cup of water.
