Cook the Quinoa:
Rinse quinoa under cold water to remove bitter coating.
Add quinoa and 1½ cups water to a medium saucepan. Bring to a boil over high heat.
Reduce heat to low, cover, and simmer for 15 minutes until water is absorbed.
Remove from heat and let stand covered for 5 minutes. Fluff with a fork and let cool completely. You should have about 2 cups cooked quinoa.
Make the Peanut Dressing:
Add peanut butter and honey to a microwave-safe bowl. Microwave for 10-20 seconds until slightly softened.
Whisk until smooth and combined.
Add grated ginger, soy sauce, red wine vinegar, sesame oil, olive oil, and sriracha. Whisk vigorously until smooth and creamy.
If dressing is too thick, add water one teaspoon at a time until desired consistency is reached. Taste and adjust seasonings as needed.
Dress the Quinoa:
Pour half of the peanut dressing over the cooled quinoa. Toss gently but thoroughly to coat every grain.
Prepare the Vegetables:
Shred red cabbage into thin strips. Dice red bell pepper into small cubes. Finely chop red onion.
Shred carrots using a box grater or julienne peeler. If using frozen edamame, thaw completely.
Chop cilantro roughly, including tender stems. Slice green onions thinly.
Assemble the Salad:
In a large mixing bowl, combine red bell pepper, red onion, cabbage, carrots, edamame, and cilantro. Toss together gently.
Add the dressed quinoa to the vegetables. Fold everything together carefully using a large spoon, being careful not to mash the vegetables.
Add more dressing gradually to taste. You may not need all of it.
Serve:
Right before serving, sprinkle cashews over the top and garnish with reserved chopped green onions.
Serve cold or at room temperature. Enjoy!
