Luncheon meat is a canned food, eat as little as possible. I have not eaten this kind of vegetarian ham you mentioned, but I think it should be tofu skin cut into the desired size, put the cut luncheon meat on one end and rolled up. The one that is cooked in the pan afterward can be tied with a thread to avoid opening up, and the thread is cut when it comes out of the pan.
Can be steamed and drizzled with sauce to eat, the sauce can be done so Garlic slices under the frying pan and then add soy sauce and oil.
