Combine extra virgin olive oil with lemon juice then season with onion, jalapeno, minced garlic, thyme, and cinnamon. Stir well.

Store in the fridge to keep it fresh.

After 2 hours, remove the marinated chicken from the fridge and thaw at room temperature.

In the meantime, preheat a grill over medium heat then wait until it is ready.

Place the marinated chicken thighs on the grill until cooked through. Occasionally, brush the chicken thighs with the remaining marinade.

Remove the grilled chicken thighs from the grill and arrange on a serving dish.

Serve and enjoy.
