Poke is simply raw fish (blue fin or yellow fin tuna) cut up into chunks, with some chopped round onions, green onions (scallion),a little bit of soy sauce (make sure it's Japanese soy sauce and not Chinese soy sauce...some Japanese soy sauce brands are Kikkoman or Aloha) and a little bit of toasted sesame oil.

In Hawai'i, they also add in some limu (seaweed) and kukui nut paste (called inamona) but if you live on the Mainland, those things will be hard to find. You can also make poke with cooked octopus (called tako poke).
