Preheat oven to 180 degrees C. Open the rolls and lay out on a baking tray.
Heat beef consomme and water in a medium saucepan over medium-high heat to make a rich beef stock. Place the roast beef in the stock and warm for 3 minutes. Arrange the meat on the rolls and top each roll with 2 slices of provolone.
Bake the sandwiches in the preheated oven for 5 minutes or until the cheese just begins to melt. Serve the sandwiches with small bowls of the warm broth for dipping.
