I used Umeboshi (pickled plum), Okaka (bonito flakes), and Tuna. For Umeboshi, deseed the plums then divide the flesh into three chunks. For Okaka, place bonito flakes into a small mixing bowl and combine with soy sauce and mirin. For Tuna, drain the brine or olive oil and mix with 1 tbsp mayonnaise.
