In a hot skillet, add olive oil, garlic, and roast. Sear roast for about 3 minutes on each side (until browned)
Place roast in the slow cooker and sprinkle the top with the ranch dressing mix and the au jus mix. Place peppers on top of the mixes, and add the butter. Add about 1/3 to 1/2 cup of the pepper juice too.
Cook over low heat for 8 hours. Serve with noodles, rice or mashed potatoes.
Note: No need to add any water or broth - it makes it's own!
I prefer to serve over homemade egg noodles (see recipe). If no time to make the noodles, Reames frozen egg noodles will do.
