Roast pig is something that is found at all Hawaiian luau. I personally would pass on the poi. It really doesn't taste very good. They make macaroni, potato salad and shredded potatoes salad with mayonnaise. Salt and pepper. That is served with the pig.
List of Ingredients
4-5 pound pork butt
1 Tbsp liquid smoke
2-1/2 tbsp Hawaiian salt or sea salt.
Recipe
Preheat oven to 325º. Rub pork with liquid smoke and 1-1/2 tbsp of Hawaiian salt. Wrap pork in foil and seal completely. Place pork in roasting pan and bake for 5 hours. After baking, shred pork, sprinkle with the remaining Hawaiian salt. Make about 10 serving.
