Preheat oven to 350.  Prepare Au Jus mix according to package instructions.  Slice the entire package of Hawaiian rolls into.  You will have 12 tops and 12 bottoms still joined together.  Place the bottoms in a baking dish.  Pour a small amount of au jus over them, do not drown them.  Add 1 large slice of prime rib to each roll and then top with a slice of provolone cheese.  Spoon a little more of the au jus over the tops of the rolls.  Bake uncovered until the cheese is melted and the tops are golden brown.  When done, cut them apart into 12 separate rolls.  Serve with the rest of the au jus in a bowl for dipping.
