I got this recipe from Alex's aunt several years ago and love it. Just mix all the ingredients together in a crock pot and the meat and au jus come out perfectly when you're ready to eat.
Italian dressing seasoning and banana peppers work together to give the meat its flavor. You can spice it up by using hot pepper rings in place of mild. Serve on wheat hoagie rolls with whatever cheese you prefer. We like provolone or pepperjack around here :)
