In a skillet, brown the lamb chops on both sides in oil; drain. Combine the orange juice, teriyaki sauce, orange zest, curry and garlic; pour over lamb. Cover and simmer for 15-20 minutes or until meat is tender. Remove chops and keep warm.
Combine cornstarch and water until smooth; stir into pan drippings. Bring to a boil; cook and stir for 2 minutes or until thickened. Serve lamb and gravy with rice if desired.
