Mix the marinade ingredients together in a small bowl and set aside.
Chop chicken breast in 2 inch squares (the best you can with lopsided meat.)
Chop bell pepper and onion into 1-2 inch squares.
Place chicken pieces into a quart size bag. Place veggies into a gallon size bag. divide marinade into each bag. Let sit for at least 30 minutes.
On soaked wooden or metal kabob sticks, alternate veggies and meat. This should make 12-15 kabobs.
On medium heat, cook on the grill for 5-8 minutes each side until chicken is thoroughly cooked.
Remove from the grill, let cool then enjoy!
