Ingredients: breadcrumbs, fresh beef, onion, egg, cheese, soy sauce, oyster sauce, cracked black pepper, lettuce, tomato, green pepper, ketchup, salsa

Step 1: Chop half an onion into cubes and use a meat grinder to make chopped onion.

Step 2: Wash 300g of beef, cut it into cubes, and put it into a meat grinder to make the beef mixture. Put the ground beef mixture into a bowl, add the grated onion, pour in a proper amount of water starch, and put in 1 egg, and mix it with chopsticks in one direction so that the beef can fully absorb the water starch and the egg mixture, and the beef mixture will be more smooth and tender.

Step 3: Add 1 tablespoon of soy sauce, oyster sauce, a pinch of salt, a pinch of sugar, 1 tablespoon of cracked black pepper, and finally half a bowl of breadcrumbs to the ground beef, and stir well with chopsticks in one direction. The breadcrumbs can lock the moisture in the beef, and the meat mixture tastes soft and tender without firewood.

Step 4: Grab a ball of ground beef and roll it back and forth between your hands a few times to round up the meat, then gently flatten it into a patty about the same diameter as the hamburger embryo.

Step 5: Brush the bottom of a pan with oil, add the beef patties, and sauté over medium-low heat until the bottom of the patties darken, then flip and cook the other side until both sides are nicely browned.

Step 6: Cover the top of the beef patty with a slice of cheese. The residual heat from the beef will soften the slice of cheese so that it will fit snugly into the patty, and place the patty on a plate.

Step 7: Take out the hamburger embryo you made last time, and then prepare lettuce, tomato, green pepper slices and other side dishes, cut the bottom one-third of the height of the bottom of the position, the bottom side of the squeeze on the ketchup, put in two pieces of lettuce leaves, lettuce leaves squeeze on the salsa, put on the beef patty with cheese, and then put in a piece of green pepper rings, squeeze a little salsa, and then put in a slice of tomato, squeeze on the salsa, and then finally put in another piece of the embryo hamburger.

Step 8: Gently press it so that all the ingredients fit together and a beef burger is assembled.

Step 9: The rest of the beef patty can be balled up and put into a plastic bag, pressed into a patty, put it in the refrigerator to freeze, and then fry it directly when you eat it, fry it and eat it directly or clip it to the burger can be.
