The first thing you need to put the broth to cook. Peel the onion and cut it in half, cut the celery into two halves, carrots in thick slices, greens. Pour water into a saucepan, put the prepared vegetables and put them on a large fire. When the water boils, add salt and pepper, reduce the heat to a light boil and leave the broth to boil for about 30 minutes.
