- To prepare marinade, stir together soy sauce, rice vinegar, sesame oil, ginger, sugar and garlic in a small mixing bowl. Stir in tuna, cover and refrigerate for 20 minutes. Pour into a strainer; drain off and discard excess marinade.
- To prepare Tuna Poke Pickups, peel cucumber and cut in half lengthwise. Scoop out the seeds with a small spoon. Cut each half into 8 pieces, slightly on the diagonal. Top with equal amounts of marinated tuna and a small dollop of wasabi sauce. Sprinkle with sesame seeds and thyme.
Cut a small slice off the bottom of each cucumber piece to make them stand up.
