Preheat the oven to 400°F.

Place the marinade ingredients in a bowl and mix.

Add the chicken cubes and coat the chicken with the marinade. Pour into a resealable plastic bag and place in the refrigerator. The chicken should marinate for at least 15 minutes or up to 8 hours.

Drain the chicken. Take one wooden skewer and insert one piece of chicken. Then, add a piece each of mushroom, pepper, and cherry tomato. Repeat one more time starting with the chicken and ending with the tomato.

Place the skewers on a cookie sheet lined with foil. Bake in the oven for 15 to 17 minutes or until the chicken is no longer pink in the middle.
