HAWAIIAN GRILLED PORK CHOPS

1 can (20oz) pineapple slices, undrained
6 (1-inch thick) trimmed pork chops
1/2 cup soy sauce
1/3 cup vegetable oil
1/4 cup minced onion
1 clove garlic, minced
1 tbs brown sugar

Drain pineapple, reserving 1/4 cup juice. Set pineapple aside. Place chops in a large shallow dish. Combine reserved pineapple juice, soy sauce, oil, onion, garlic, and brown sugar, mixing well. Pour over chops; cover and marinate in refrigerator 2 hours or more. Remove chops, reserving marinade. Grill over medium coals 40 to 45 minutes, turning frequently and basting with marinade.
