Combine ingredients for marinade in a plastic bag, then add in diced chicken. Let chicken marinate on counter top for 10 minutes.
In a skillet, heat 1 tbs. of olive oil and when warm, add chicken pieces with tongs, shaking off any excess marinade. Let chicken cook for 3-4 minutes without touching, then toss to brown other sides and cook for another 3 minutes.
Add in diced onion, bell pepper and coleslaw mix to pan and sauté until soft, about 4 minutes. Check to make sure chicken has cooked through by cutting through one piece!
Serve stir fry on it's own or over cauliflower rice, veggie rice or coconut rice!
