Combine all ingredients except chicken in a food processor or blender. Blend until smooth. In a large Ziploc bag, add chicken and marinade. Seal and marinate in fridge minimum 2-3 hours or up to 12 hours.
Add about 2 tablespoons olive oil to a large cast iron skillet. Heat on medium-high until oil is fragrant. Add chicken and cook 5-6 minutes per side, until internal temperature reaches 165 degrees.
Remove chicken from the pan and let rest 5-10 minutes before dicing.
