Prepare bread crumbs, fresh beef, onion, eggs, cheese, soy sauce, oyster sauce, chopped black pepper, lettuce, tomato, green pepper, tomato sauce and salad dressing.

Step 1: cut half an onion into pieces and beat it into pieces with a cooking machine for later use.

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

Step 3: Add 1 spoon of light soy sauce, appropriate amount of oyster sauce, a small amount of salt, and a small amount of sugar to the stirred beef stuffing, add 1 spoon of chopped black pepper, and finally put half a bowl of bread crumbs, and stir well 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 with your hands, round it back and forth with your hands several times to reunite the meat stuffing, gently flatten it and press it into a meat pie with the same diameter as the hamburger embryo.

Step 5: Brush the bottom of the pan with oil, add the beef patties, fry them on medium and small fire until the bottom of the beef becomes dark, then turn over and fry the other side until both sides are dark, and then turn off the heat.

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

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

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

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