American Sliced Pork Garlic Stem

It sounds like you are trying to learn about a specific dish that you have come across in restaurants in the USA, which you described as "American sliced pork garlic stem." I'm having a little bit of difficulty finding a specific dish that matches that exact description, but I can provide some information that may be helpful.

One possibility is that you are referring to a dish called "Garlic Pork" or "Garlic Pork Belly" which is a popular dish in many Asian restaurants in the United States. This dish typically features thinly sliced pork belly that has been marinated in a mixture of garlic, soy sauce, and other seasonings, and then quickly stir-fried. The pork belly is often served with steamed vegetables and rice.

Another possibility is that you are referring to a dish called "Bulgogi" which is a popular Korean dish made with thinly sliced beef or pork that has been marinated in a mixture of soy sauce, garlic, sugar, and other seasonings, and then grilled or pan-fried. Bulgogi is often served with steamed rice and a variety of side dishes.

If neither of these dishes match what you are looking for, I would recommend checking with the restaurant directly to get more information about the dish. They should be able to provide you with a detailed description of the ingredients and preparation method.
