Method:
Preheat oven to 425°F. In a small bowl, combine apples, cranberries, nutmeg and pepper. Stuff all of the fruit filling snugly down through the center of the roast, working from both ends. Season roast all over with salt and arrange in a roasting pan.
Roast, uncovered, until deep golden brown and crisp, about 35 minutes. Reduce temperature to 325°F, tent roast with foil and continue roasting until a thermometer inserted into the thickest part of the meat (not the filling) registers 155°F. The temperature will continue to rise out of the oven. Set aside for 15 minutes to let rest, then cut into thin slices and serve hot or at room temperature, drizzled with pan juices.
