In a large bowl, combine the mixed salad greens, shredded chicken, carrots, red bell pepper, cucumber, cilantro, and green onions. Toss gently to combine.
In a separate bowl, whisk together the peanut butter, soy sauce, lime juice, honey, sesame oil, garlic, and ginger until smooth. If the dressing is too thick, add water a tablespoon at a time until desired consistency is reached.
Drizzle the dressing over the salad and toss until everything is evenly coated.
If using, sprinkle chopped peanuts on top for added crunch.
Serve immediately or chill in the refrigerator for up to 30 minutes before serving for a refreshing taste.
