Preheat the oven to 200 degrees F. Using a sharp knife, score the top of the bologna several times. Season the bologna with salt and pepper. Place the bologna on a roasting pan. Bake the bologna for 6 to 7 hours, or until the outside of the bologna is completely charred. Remove the bologna from the pan and place on a large platter. Serve the bologna hot with rolls and whole-grain mustard.
