In a large bowl, combine the green cabbage, red cabbage, carrots, red bell pepper, scallions, and fresh cilantro.
In a separate bowl, whisk together the creamy peanut butter, rice vinegar, lime juice, soy sauce, toasted sesame oil, neutral oil, light brown sugar, fresh ginger, garlic, and sriracha until smooth. Whisk in the warm water until the dressing is glossy and pourable.
Add the chopped roasted peanuts to the vegetables. Pour the dressing over the slaw and toss thoroughly until everything is evenly coated.
Let the slaw stand for 10 minutes to lightly wilt and meld flavors; it should soften slightly while staying crisp.
Toss again, transfer to a serving platter, and top with additional roasted peanuts. Serve with lime wedges for squeezing at the table.
