if it is fresh and you like sashimi, cut into about 1 inch thick fillets, sprinkle some sugar and salt on side, then sear that side (cook only on one side) on a hot pan till it is caramelized and crispy. u can get fancy with presentation on a salad, lentils, pasta, orzo salad, fried spinach (yes fried spincah, heat about 1-2 inch of olive oil, or other oil if u dont like olive oil in a deep pan and quickly fry the spincah in it just till it is wilted and turns dark green)
