Set your oven to 425°F and line a baking tray with parchment to make cleanup simple.

Place the frozen Texas Toast on the tray and follow package directions to bake. Flip them during the cooking to get golden edges, usually around 8 minutes.

As the bread is baking, combine the au jus mix with 3 cups of cold water. Prep it according to the package, then let it stay warm on the stovetop.
04 -
Once the au jus is warm, add the beef to it. Let the slices soak for a bit and heat up completely.
05 -
Lay the cooked Texas Toast back on the baking tray. Put half a slice of cheese on each piece first.
06 -
With tongs, grab the warm roast beef from the au jus. Evenly stack it across all 8 pieces of toast.
07 -
Add the remaining half slices of provolone over the beef to complete the cheesy layer.
08 -
Put it all in the oven again for a few minutes. Heat until the cheese melts and shows a light golden shade.

Take everything out of the oven and, if you like, scatter a little parsley on top. Serve right away with bowls of warm au jus for dipping.
