Chicken cutlet rice is a popular dish in Taiwan. It is not always made from a pre-packaged seasoning mix. The chicken cutlet is usually made by marinating the chicken in a mixture of soy sauce, ginger, garlic, and other spices, and then coated with flour or breadcrumbs before frying. The rice is typically cooked separately and served with the crispy chicken cutlet on top. Some restaurants or convenience stores may use pre-packaged seasoning mixes for convenience, but it is not a requirement for making chicken cutlet rice.
