Cook quinoa according to package directions, which typically involves rinsing it well before boiling in water until fluffy.
In a microwave-safe bowl, combine creamy peanut butter and honey, heating them together in the microwave for about 10-20 seconds until warm and easy to mix. Stir until smooth before adding freshly grated ginger, low-sodium soy sauce, apple cider vinegar, sesame oil, olive oil, and Sriracha hot sauce; mix until creamy.
In a large mixing bowl, toss together shredded red cabbage, diced red bell pepper, chopped red onion, shredded carrots, shelled edamame, and chopped cilantro until evenly distributed.
Add the cooled quinoa to the bowl of vegetables along with half of the prepared dressing; toss well to combine all ingredients thoroughly while ensuring each component is coated nicely.
Add as much of the remaining dressing as you prefer based on taste preferences; then gently fold in halved cashews for added crunch before garnishing with chopped green onions.
