Slow Cooker Mississippi Roast

Wow, wow, and more wow!  That's all I have to say about this one!  It's super simple to put together and the taste is amazing!!!  Make sure to use the au jus gravy mix.  It gives it such a distinct flavor!  Also, use unsalted butter because the recipe runs a little on the salty side and you don't want to oversalt it.  You can serve it with mashed potatoes, rice, pasta, veggies, or like we did, as a sandwich.  Either way, it's out of this world delicious!  Enjoy!
-1/4 cup water
-3 lbs roast beef (I used rump roast,but any cut works just fine)
-1 packet dry ranch seasoning mix
-1 packet dry au jus gravy mix
-1 stick unsalted butter, cut into small pieces
-1 cup sliced pepperoncinis, drained
Pour water on bottom of slow cooker.  Add the beef.  Sprinkle the ranch and gravy mixes on top.  Place the butter pieces over the seasonings.  Top is all with the pepperoncini slices.
Cover and cook on low for 8 hours.  Shred the meat in the crockpot, then mix it well with the gravy.  Serve as a sandwich or with your chosen sides.  Enjoy!
