Heat oven to 350°. Place pork, fat side up, on cutting board. Cut horizontally
through center of pork almost to opposite side. Open pork like a book. Layer dried
fruits and onion in opening. Bring halves of pork together; tie at 1-inch intervals
with kitchen twine. Turn pork so fat is on bottom. Mix salt, thyme, cinnamon and
pepper in small bowl; rub into pork.
