Combine all chicken marinade ingredients in a large bowl. Whisk together well.
Place chicken in a large ziploc bag and pour marinade over chicken.
Let marinade for 2 hours up to overnight.
When ready to cook the chicken, prepare a cast iron pan or a grill. Preheat to get the skillet or grill hot on a medium heat, for at least 5 minutes.
Using tongs add chicken to pan and sear for 5-7 minutes on each side, until slightly charred.
Once cooked through, remove from heat and let rest for 5 minutes. Then chop into bite-sized pieces and set aside until ready to serve.
