Prep the veggies: Add the cabbages, carrots, bell pepper, green onions, edamame, and cilantro to a large bowl.
Toss to combine.
Make the dressing: In a jar or small bowl, whisk peanut butter, soy sauce, maple syrup, lime juice, rice vinegar, sesame oil, ginger, and garlic. Add warm water a little at a time until smooth and pourable.
Adjust to taste: Add sriracha for heat, more lime for brightness, or maple syrup for balance. It should taste bold and slightly tangy.
Toss the slaw: Pour most of the dressing over the veggies and toss until everything is lightly coated.
Add more dressing as needed.
Finish and serve: Sprinkle with chopped peanuts and any add-ins. Serve right away for maximum crunch.
For a heartier bowl: Top with baked tofu or extra edamame and a squeeze of lime.
