Got this recipe from a Hawaiian friend of mine.
Pork butt. Kosher or coarse Hawaiian salt
Liquid smoke. Green cabbage
Onion. Black pepper corns
White sticky rice. HD foil
Turkey oven bag. Cooking oil

Pre-heat oven to 300* F.

In a roasting pan, place several sheets of foil, and the open oven bag. Cover butt with liquid smoke(use gloves),then cover butt in coarse salt- be generous this is salting the whole meal. Close up oven bag and wrap tightly with foil. Add water to the roaster ions inch deep. Cook in oven at 300� for one hour, lower temperature to 250� and cook till meat falls off bone and can be pulled easily.

Prepare white rice per instructions on package. Dice onion and saut� in large pan or wok. Chop cabbage into large strips, coat lightly with oil add to onion, cook cabbage down till it softens/wilts to your Liking. Add shredded pork to cabbage.

Serve on plate over rice. And enjoy, even better the next day.
