Cut the cabbage into small bite-sized pieces. Slice off the ends of the cucumber and julienne it. Place both in a bowl, add salt, and massage. Let sit for 5 minutes, then thoroughly squeeze out excess water.

Remove the tendon from the chicken tender. Place the chicken and cabbage in a microwave-safe container, sprinkle with sake, cover loosely with plastic wrap, and microwave at 600W for 4 minutes. Let cool, then shred the chicken into large pieces.

In a bowl, mix the dressing ingredients (ground sesame, vinegar, soy sauce, and sugar) until well combined.
