Prepare the aromatics and herbs by finely chopping the garlic, ginger, cilantro, and jalapeño peppers.
In a bowl, combine soy sauce, fish sauce, olive oil, sugar, garlic, ginger, jalapeño, cilantro, and freshly ground black pepper. Mix it thoroughly and set aside.
Remove the fats from the thawed chicken, then add it to the marinade. Massage the marinade into every crease of the chicken.
Cover the chicken and marinate it for a minimum of 30 minutes. The longer it marinates, the tastier it is.
In medium-high heat and 2-3 tablespoons of oil, heat up the pan well.
Once heated, place the chicken to sear for 5-7 minutes. Do not touch it so it creates a beautiful golden brown crust.
Once ready to flip (freely unsticks to the pan), flip and do the same to the other side.
Stick an internal thermometer to the thickest part of the chicken and once it reads 165F, it is done.
Serve hot and enjoy!
