Mix together marinade ingredients. Reserve ¼ cup marinade for after baking.
Cut chicken into 1 ½" cubes and add to a large ziploc bag. Add in the marinade. Massage into the chicken. It's important that your chicken is cut the same size! Marinate in the fridge 2-4 hours.
Soak skewers in water while your chicken marinates.
When your're ready to assemble your chicken kabobs, have a baking sheet and your skewers ready to go. Add 4-5 chicken cubes to each mini skewer alternating with a pepper and onion slice.Set onto a non-stick baking sheet or a regular baking sheet lined with parchment paper.
Bake on top rack at 425°F for 8-9 minutes or until chicken is cooked through. Do not overcook or your chicken will be dry.**Use a meat thermometer to test the internal temp! You want your chicken at 165°F.
When they come out of the oven, brush them once more with the reserved marinade.
Serve skewers with sauces on the side.
Notes
Make sure not to squeeze the chicken together or it will lead to uneven cooking. Overcooking your kabobs will lead to dry chicken.
