Prepare apple-nut stuffing by mixing all ingredients. Cut a deep pocket in each pork chop on meatiest side of bone. Press about 1/3 cup stuffing into each pocket. Secure with toothpicks. Mix margarine, orange juice and nutmeg. Cover and grill pork 4-5" from medium-low coals about 40-45 minutes, brushing occasionally with orange juice mix and turning 3-4 times, until pork is no longer pink in center. Remove toothpicks.
