Combine all ingredients for the marinade in a bowl.
Cut the chicken into equally sized squares.
Put the chicken in the marinade and make sure all pieces are well covered.
Let it sit in the marinate for at least 30 minutes.
When time to grill the chicken, remove excess marinade and put on skewers.
Put on the grill and let it grill for 15-20 minutes (depending on how big the chicken pieces are).
If making in a grill pan: Preaheat a grillpan over medium/high heat with some olive oil.
Preheat the oven to 150 degrees Celcius.
Grill the chicken in the pan on each side until you have grill marks.
Put the chicken skewers in a oven safe dish and bake in the oven for 15 minutes (or until chicken is done).
By baking the chicken on lower temperature, such as 150 degrees its easier to not overcook them. This way it gets really juicy and tender.
