I met a lifeguard in Kauai that was making the most grass roots sashimi I’ve ever seen. His friend caught the fish right in front of his patrol, and he filleted it right on the cement footing of his tower. Then he bummed some soy sauce from a camper nearby and some wasabi from another lifeguard. He just cut the fish into chunks, added soy sauce and wasabi, and was good to go. Good quality fresh fish right from the ocean needs no more prep than that. But if your going to do this yourself remember to buy sushi grade fish, or you’ll probably get the trotts. Or catch it yourself.
