In a large bowl, combine the cooked quinoa, shredded cabbage, julienned carrot, sliced bell pepper, cilantro, green onions, and edamame (if using).
In a separate small bowl, whisk together the rice vinegar, soy sauce, lime juice, honey, sesame oil, ginger, and chili flakes until well combined.
Pour the dressing over the quinoa mixture and toss gently to coat everything evenly.
Top with chopped peanuts for an extra crunch.
Serve chilled or at room temperature for the best flavor.
