Add the meatballs and cook until tender for 20-25 minutes.
P.S. The meatballs were prepared by me in advance and frozen, which is very convenient to save time. And they are prepared like this:
combine the finished minced meat with a chicken egg, add salt, finely chopped onion, herbs if desired, knead until smooth, moisten your hands with cold water (so that the minced meat does not stick) and form balls, which are then dipped into boiling broth or water. Cook the meatballs for about 20-25 minutes.
