After putting roast into your crock pot, sprinkle the ranch dressing and the onion soup mix on top.
Drop the butter and peroncinis on top of the meat, as well.
Cover and cook on LOW for about 8 hrs or so, until the beef pulls apart easily. Take two forks and shred meat, mixing back into the juices in crock pot.
Warm oven to 400* and place your hoagie buns on a baking sheet and toast for a couple minutes.
Remove buns from oven and fill with beef. Top each sandwich with 1-2 slices of provolone cheese. Place back into oven until cheese is melted.
Remove sandwiches from oven and top with gardiniera, if desired. ENJOY!!
