In a large bowl, combine the shredded cabbage, carrots, cooked chicken, bell peppers, cilantro, green onions, and rice noodles. Toss gently to mix all the ingredients evenly.
In a separate small bowl, whisk together the soy sauce, rice vinegar, sesame oil, honey, minced garlic, grated ginger, and red pepper flakes until well combined.
Pour the dressing over the salad mixture and toss until everything is evenly coated.
If desired, sprinkle crushed peanuts on top for added crunch.
Serve immediately or chill in the refrigerator for about 30 minutes to allow the flavors to meld together.
