Tap into the spirit of Aloha by serving this modern iteration of the popular Hawaiian appetizer salad. In this recipe, diced Ahi tuna loin is combined with an onion, ginger, scallion, soy and sesame sauce, and served with lettuce cups and fried wontons. You definitely have to find a good source for sashimi-grade tuna. After that there is very little prep time, so you can be as relaxed as any beach-going local.
