This pot roast has been all over Pinterest. I decided to give it a try, and, let me tell you, it is GREAT! It is also SUPER easy to make. Throw the roast in the crock pot, sprinkle with Au Jus mix, Ranch mix, add a stick of butter and some pepperoncini peppers. That is it. This roast has no liquid added to it. Don't worry, I promise it turns out great. It actually makes a ton of its on gravy as it cooks. We served this over some parmesan risotto, and we both wanted to lick out plates. We had the leftovers the next night and this was as good (probably better). I don't know why it is called "Mississippi Pot Roast", but who cares? It was delicious!
