Teriyaki Pork

1 package scallopini pork, as thin as possible pork that you can get
1/4 cup brown sugar
1 cup teriyaki sauce
1/2 cup soy sauce
1 tablespoon salt
1/2 cup water

1/2 cup pineapple juice
1/2 red onion chopped
1 gallon sized bag

Put everything except the pork in the gallon sized bag. Then place the pork in the bag . Marinate for at least 30 min. Cook on the grill or in the oven. The grill is best, really gives that smokey flavor. Cook until the pinkish brown of the pork turns to a grey white color. With the thin cut about 6 min on either side.
