Combine all ingredients for sauce in a bowl. Marinate chicken with sauce, and keep in refrigerator for 20-30 minutes.
Heat a frypan (around 24-28cm) over medium heat, then add some oil. Add marinated chicken, cabbage and sweet potato into pan and fry until cabbage has softened and chicken is almost fully cooked. This should take around 7-10 minutes.
Finally, add mozzarella cheese and cook until cheese has melted. Serve with rice.
