6 pork chops -- 1 inch thick
1/4 cup pineapple juice
1/2 cup soy sauce
1/3 cup vegetable oil
1/4 cup onion -- minced
2 cloves garlic -- minced
2 tablespoon brown sugar

Drain pineapple and pour 1/4 cup of the juice into a bowl. Combine with soy sauce, vegetable oil, onion, garlic, and brown sugar. Place pork chops in a large resealable bag. Pour marinade mixture over top.

Seal bag and refrigerator for 2 hours. Preheat grill. Remove pork chops from marinade and place on hot grill. Cook for about 20 minutes or until done. Turn half way through cooking time and baste with remaining marinade. Top with pineapple slices during the last few minutes of grilling
