Add dry quinoa to a small pot with 1 cup of water. Cover and bring to a boil, then reduce to a low simmer and cook about 15-20 minutes until water is absorbed. Remove the lid and let sit 5-10 minutes, then fluff with a fork.
Cook edamame:
Meanwhile, in a small pot boil the remaining water (1 1/2 cup, as recipe is written) and add fresh or frozen edamame. Boil 5 minutes, or until edamame has become soft (but not mushy). Drain and set aside.
Make sauce:
While the quinoa and edamame is cooking, make the sauce by combining peanut butter, soy sauce (or tamari), lime juice, maple syrup, rice vinegar, sesame oil, ginger powder (or fresh ginger), salt, and red pepper flakes (if using) to a small bowl. Whisk to mix well, then set aside.
Assemble salad:
When quinoa and edamame have cooked the sauce is ready, to a large salad bowl add red cabbage, green cabbage, grated carrots, cilantro, green onion, peanuts, cooked quinoa, and cooked edamame. Drizzle the salad with the peanut sauce, then toss to combine.
