Make the dressing: Blend peanut butter, soy sauce, lime juice, maple syrup, garlic, and optional ginger until smooth. Add 2 to 4 tablespoons of water and blend again until the dressing is creamy and pourable.
Prep the vegetables: Add the green cabbage, red cabbage, carrots, bell pepper, green onions, and cilantro to a large bowl.
Toss the salad: Pour about half of the dressing over the salad. Toss well until everything is evenly coated. Add more dressing as you like.
Finish and serve: Top with chopped peanuts. Serve right away for the best crunch. Add lime wedges on the side for extra freshness.
