Prepare bread crumbs, fresh beef, onions, eggs, cheese, soy sauce, oyster sauce, chopped black pepper, lettuce, tomatoes, green peppers, ketchup and salad dressing.

Step 1: Cut half an onion into sections and break it into pieces with a cooking machine for later use.

Step 2: Wash 300 grams of beef, cut it into pieces, and put it into a meat grinder to stir it into beef stuffing. Put the minced beef into a bowl, add the minced onion, pour a proper amount of water starch, then add 1 egg, and stir in one direction with chopsticks, so that the minced beef will be smooth and tender.

Step 3: Add 1 tbsp light soy sauce, appropriate amount of oyster sauce, a little salt and a little sugar to the stirred beef stuffing, add 1 tbsp chopped black pepper, and finally put half a bowl of bread crumbs and stir evenly in one direction with chopsticks. Bread crumbs can lock the moisture in beef, and the meat stuffing tastes soft and tender.

Step 4: Grab a mass of beef stuffing by hand, circle it back and forth by hand for reunion, gently flatten it, and press it into patties with the same diameter as the hamburger embryo.

Step 5: Brush the bottom of the pot with oil, add the beef patties, fry them on medium and small fire until the bottom of the beef patties turns black, then turn over the other side to both sides and turn off the heat.

Step 6: Cover the beef patties with a slice of cheese. The residual temperature of beef can soften the cheese slices, so that the cheese slices will stick to the beef patties. Put the prepared cheese beef patties into the plate for later use.

Step 7: Take out the hamburger embryo made last time, then prepare side dishes such as lettuce, tomato slices and green pepper slices, cut from the bottom one third, squeeze tomato sauce at the bottom, put two lettuce leaves, squeeze salad dressing on lettuce leaves, put cheese beef patties, put green pepper rings, squeeze some salad dressing, put a tomato, squeeze salad dressing, and finally put a hamburger embryo.

Step 8: Press it gently to make all the ingredients fit together, and a beef burger will be assembled.

Step 9: The remaining beef stuffing can be stuffed into fresh-keeping bags, pressed into patties, frozen in the refrigerator, fried directly when eating, eaten directly or eaten with hamburgers.
