Cook for about 10 minutes or until instant read thermometer reach 165 degrees F. Remove from heat and when cool enough to handle dice the chicken breasts.
Meanwhile prepare the vegetables. In a large bowl combine the cabbage, carrots, green onions, cilantro, and sesame seeds, tossing to combine.
In a small bowl, combine the orange juice, olive oil, rice vinegar, fish sauce, and ginger. Gently stir until mixed, then pour over the salad. Toss to coat.
