If you haven't already, put a small pot of water to boil for the edamame. Cook according to package directions (usually 5 min!). Drain and rinse well with cold water.
In a medium salad bowl, toss the cucumber, cabbage and edamame with the vinegar and salt. Then add half the peanut sauce and toss WELL.
Add more peanut sauce if desired, then toss with the peanuts and cilantro and serve.
