Poke (pronounced POH-kay) tuna is tuna sashimi marinated in a flavorful blend of sesame oil, ginger, garlic, lime, and soy sauce, topped with scallions, sesame seeds and nuts. I believe kukui nuts or macadamia nuts are the classic nuts to use, but you can substitute peanuts if you haven’t got any of those lying around. Although it seems exotic, this dish is actually very easy. Perhaps this is obvious, but there is no heat involved, so it’s fabulous for summer. It is usually accompanied by seaweed salad, either mixed in with the tuna or on the side.
