Stir together marinade and orange juice in a small bowl. Remove and reserve 1/3 cup marinade mixture. Place pork and remaining marinade mixture in a large zip-top plastic freezer bag, turning to coat; seal and chill 30 minutes, turning occasionally. Remove pork from marinade, discarding marinade.
Grill pork, covered with grill lid, over medium-high heat (350° to 400°) 7 to 8 minutes on each side or until pork is done.
Sauté green onions in hot oil in a 1-quart saucepan over medium heat 1 minute. Stir in reserved marinade mixture, brown sugar, and orange rind. Bring to a boil over high heat, and cook, stirring constantly, 1 minute or until sauce is thickened. Serve sauce over pork.
James's tip: Save money on pork chops by purchasing a whole pork loin on sale and slicing your own boneless pork chops.
