Add the garlic and Marinade to the chicken, stir to combine well, marinade for 30 minutes. Heat up a skillet (cast-iron preferred) on medium heat. Add the oil. Transfer the chicken to the skillet and cook on both sides, until they turn golden brown and cooked. Add the remaining Marinade to the skillet, as soon as it thickens, turn off the heat, top with some sesame seeds (if using) and serve the chicken immediately.
