Whisk the dressing: In a small bowl or mason jar, combine sesame oil, lime juice, soy sauce, honey, grated garlic, ginger, and red pepper flakes. Whisk (or shake) until emulsified.
Assemble the greens: In a large serving bowl, toss the green cabbage, red cabbage, carrots, scallions, cilantro, and mint.
Toss and garnish: Drizzle the dressing over the vegetables right before serving and toss well to coat. Finish with toasted sesame seeds or crushed roasted peanuts across the top for crunch.
