Start by preparing your fresh ingredients for the slaw. Finely shred the green cabbage and purple cabbage if using. Julienne the carrots, then slice the red bell pepper and green onions. Arrange in a large mixing bowl.

In a separate bowl, combine sesame oil, soy sauce, rice vinegar, and honey. Whisk for about 30 seconds until well blended and slightly thickened.

Pour the dressing over the prepared vegetables. Toss gently with tongs or hands for about 1-2 minutes until well-coated.

Let the mixture sit for at least 15 minutes to enhance flavors. This resting period allows the cabbage to soften slightly.

Before serving, give the slaw a final toss and garnish with toasted sesame seeds and cilantro. Serve immediately.
