Preheat the oven to 425°F. Line a sheet tray with parchment paper.
Cook 1 box frozen garlic Texas Toast per the directions on the back of the box, mine cooked for 8 minutes, flipping halfway through.
While the toast is baking, make the 1 packet au jus gravy mix with 3 cups cold water according to the package directions.
Once the toast and au jus are ready, warm 1 pound sliced deli roast beef in the au jus.
On top of each piece of cooked toast, place a half slice of provolone cheese.
Top all of the toasts evenly with the roast beef slices.
Add the remaining half slices of provolone cheese on top.
Bake for 3-5 minutes or until cheese is fully melted. Top with dried parsley, for garnish (optional).
Serve immediately with the au jus for dipping.
