Mix all the ingredients thoroughly in a bowl and marinate for 1 hour. Bake the chicken at 375 degrees for 35 minutes or until tender. Garnish with Chinese parsley and sliced tomato wedge. Note from Titus Chan "Hoi sin gai is a quick and easy dish with strong similarities to Western methods of preparation with the exception of the use of hoi sin sauce, a deep, brown sauce that can be purchased at any Chinese grocery or oriental feed department. Those who have tasted Peking Duck will recognize hoi sin as the sauce commonly used to brush on the thin pancake in which you roll the crisp duck skin. It adds a piquant flavor to the chicken in this recipe. One may also use this sauce, omitting cornstarch and soy sauce for roast duck."
