Slice the beef and then cut the beef strips into beef granules, so that the beef stuffing has the taste of beef granules. I prefer beef granules to make beef stuffing myself. If you think the beef granules are too troublesome, you can use a meat grinder to stir the beef and stir it into minced beef.
Peel and chop ginger into ginger paste, add oil and pepper to wok, and saute pepper to get pepper oil. Add ginger into beef granules, stir in one direction, stir ginger and beef evenly, add a spoonful of water three times, stir in the original direction after each addition, and continue to add water after the beef absorbs water.
