Place all ingredients in a ziploc bag and toss well to coat the chicken and vegetables with the oil and spices. If making a double batch, you can freeze at this point. Thaw completely before proceeding.
Alternate chicken and veggies onto a kebab stick (I recommend the metal ones).
Place on the grill and cook until the chicken is cooked through.
Notes
Please note that the nutrition data below is a ballpark figure. Exact data is not possible. Also, I calculated the fat content with half the amount of oil suggested in the recipe because you won't eat the entire amount of oil once this has been on the grill. So the data only included 2 tbsp. of oil which is rather generous.
