I made a roast very similar to your recipe, and it was a HUGE hit with DH!
I even liked it, and I don't like ranch dressing or peppers. LOL!
Mississippi Roast
1 Roast
1 Pkg Au Jus Mix
1 Pkg Dry Ranch Dressing Mix
5 Pepperoncini Peppers (comes in a jar; usually found with the pickles)
1 Stick of Butter (I've used 1/2 a stick and it comes out just fine)
Put the roast in the crock pot. (You can use tenderizer if the roast isn't that great a cut.) Don't add water or other liquids. Sprinkle on the au jus mix and the ranch dressing mix. Lay the butter on top of the roast (you can cut the butter into chunks if you want). Lay the 5 peppers on top of the roast, around the butter.
Cook on low for 5-6 hours or until roast is done.
It makes its own juice, which you can make into gravy or serve as dipping sauce.
YUM!
