Make the glaze mixture: To a small bowl add in the melted butter, worceststershire sauce, 1 tbs of the Au Jus mix (we will use the remaining Au Just mix in a moment) , sesame seeds, and minced garlic stir together and set this mixture to the side.
Slice the rolls in half horizontally. Line a sheet pan with parchment paper, place the bottom half of the rolls on the bottom of the pan layer half of the provolone cheese on the rolls, then top with all of the roast beef, brush or drizzle half of the glaze on top of the roast beef, sprinkle the fried onions over the top, place the remaining cheese over the top, then cover with the top part of the rolls.
Brush or drizzle the remaining glaze on the top of the rolls.
Bake for 8-10 minutes or until the cheese is melty.
While in the oven work on the Au Jus dipping sauce: To a small pot on the stove add in the rest of the Au Jus packet and 1 1/2 cups of water bring to a simmer and whisk often until the sauce slightly thickens serve this Au Jus in a small bowl on the side of your dish to dip the sliders in.
