Persevered Pork Chicken

The dish you're referring to is likely called "Preserved Pork and Chicken," and it is a Chinese dish that can be found in some restaurants in the USA. The preserved pork is often referred to as "lap yok" (or "lap yuk") in Cantonese, and it is made by curing pork belly with salt, sugar, and spices, and then allowing it to age for a period of time.

During the aging process, the pork develops a distinct flavor and texture, becoming tender and somewhat gelatinous. The preserved pork is then typically cooked with chicken and served with rice or noodles. The combination of the savory, rich flavor of the preserved pork and the tender, juicy chicken makes for a delicious and satisfying dish.

If you come across this dish in a restaurant, I would highly recommend giving it a try. The unique flavor and texture of the preserved pork can be a real treat, and it is a great way to experience traditional Chinese cuisine. Just keep in mind that, like many traditional dishes, the flavor and ingredients can vary from one region or cook to another. So, it's always a good idea to ask the restaurant for more information about the dish and its ingredients.
