I haven't had the pleasure of visiting the South Pacific yet, but arranged for my own little virtual adventure. Hawaiian poke is usually made with ahi tuna, but here's my interpretation with fluke.
1/3 lb fluke fillet, sushi grade
dash of black sesame seeds
1/2 tsp sesame oil
2 tbsp chopped green onions
2 tbsp Taiwanese basil, thinly sliced
2 tbsp low-sodium soy sauce
1 tsp chili powder
Chop fluke into cubes (1/2 inch). Toss fluke with the other ingredients in a non-reactive bowl, and place in the fridge for a few hours. I served with a basil leaf, french breakfast radish, and rice crackers.
