Excluding chicken, add all ingredients to a blender and blend using the high setting until mixture is well combined.
To a bowl add the chicken pieces and chimichurri sauce. Let marinade 20-30 minutes. If using wooden skewers, soak in water for 30 minutes as well.
Heat an outdoor grill to medium high heat. Add chicken kebabs and cook approximately 6 minutes per side, turning once. Once internal temperature reaches 160 F remove from grill. Allow to cool slightly and remove from kebabs and serve.
