1. Ingredients: 100g beef, 400g beans, 1 egg, appropriate amount of oil, 3g salt, 10ml light soy sauce, 2g chicken powder, 2g chili powder.

2. Wash the beef and cut into shreds. Remove the tendons from the beans and cut into long sections.

3. If you want the beef to be tender and delicious, add an egg and stir evenly.

4. Pour cooking oil into the wok and heat it up to 80%, then turn off the heat and reduce the oil temperature to about 20%. That is, wait until the oil temperature is slightly cool. At this time, add the shredded beef and use chopsticks to cut it. Fry it in oil to prevent it from sticking to the pan.

5. Use the residual heat to fry the shredded beef until it changes color, then continue to fry the shredded beef over low heat for about 5 minutes. At this time, the beef is almost cooked. Fresh and tender, easier to cook.

6. After the beef is cooked, pour the beans into the pot and stir-fry.

7. Stir-fry for a few times and add appropriate amount of salt and light soy sauce to taste.

8. Beans must be cooked before they are safe to eat. Uncooked beans can prevent poisoning. Finally, add chicken powder for seasoning.
