STEP 1For the dressing, in a small bowl, whisk together all ingredients until smooth and combined. If dressing is too thick, add a splash of water. Season with salt and pepper, if needed. Set aside.
STEP 2For the salad, combine cabbage, edamame, carrot, bell pepper, scallions, cilantro, and peanuts in a large bowl. Pour dressing over the slaw and toss well to coat.
