In a small bowl, combine the mustard, pepper and 2 teaspoons syrup. Brush over both sides of pork chops. In a large nonstick skillet, brown pork in butter over medium heat for 2-3 minutes on each side. Add apple juice. Reduce heat; cover and simmer for 15-20 minutes or until meat is tender. Remove chops and keep warm.
Add pecans and remaining syrup to the skillet; cook and stir for 1-2 minutes or until blended. Serve over pork chops.
