Prepare dressing: Combine ½ cup carrots, ⅓ cup vinegar, ¼ cup onion, the sliced ginger, 2 tablespoons miso, 1 tablespoon honey and ¼ teaspoon pepper in a blender. Process until smooth, about 1 minute. With the blender running, gradually add ¼ cup neutral oil and 1 tablespoon sesame oil; continue processing until emulsified and very smooth, 20 to 30 seconds.
Prepare salad: Combine 8 ounces coleslaw mix, 2 cups edamame, 1 cup carrots and the chopped cucumber and sliced bell pepper in a large bowl; toss well. Drizzle with the dressing and sprinkle with 2 tablespoons sesame seeds; toss until evenly coated.
Divide the salad among 4 plates. Garnish with additional sesame seeds, if desired.
