In saucepan over medium heat, cook brown sugar, tomato paste, apple cider vinegar, mustard, onion powder, garlic powder, paprika, barbecue seasoning, honey and teriyaki sauce until well combined.

Cube chicken and place in large bowl. Pour sauce over chicken, saving some for basting. Marinate at least 1 hour.

Heat grill to medium heat.
