Make the marinade. Combine oil, vinegar, oregano, garlic, adobo and sazon in a bowl, mortar & pestle or food processor. Process until a smooth paste is formed and then add the bay leaves.
Prep the chicken. Chop the chicken into bite sized pieces, place in a bowl, and coat with the marinade. Marinate covered in the fridge for at least an hour (or overnight).
Grill the chicken. Thread the chicken pieces onto skewers and prep your grill surface, heating to medium heat. Grill the chicken skewers for 10 minutes on both sides, or until cooked to an internal temperature of 165 degrees.
