The sliced string beans are washed and boiled for 10 minutes in salted water. Drain the water. Wash, peel and finely chop the onion. In a frying pan, pour the vegetable oil, add the onion and fry a little. Add the beans, mix and fry for another 10 minutes on low heat.
Add the eggs, pepper, and a little salt to the beans and stir until the eggs are fully cooked (2 minutes).
Here is such a delicious bean turned out.
Fill the beans with grated cheese and cover with a lid for 2-3 minutes.
