Chop the potatoes, carrots, and onion. Bring the 2 liters of broth to a boil over high heat. Once boiling, add the vegetables and salt to taste. Reduce heat to medium and cook for 10 minutes.
In a bowl, combine the minced meat with salt and pepper to taste. Mix for about 1 minute until well combined.
Form the mixture into meatballs using wet hands.
Carefully add the meatballs to the soup. Cook over medium heat for 15 minutes until the meatballs are cooked through.
Add your choice of noodles, rice, or buckwheat to the soup. If using noodles, cook for 8-10 minutes; if using rice or buckwheat, cook for 15-20 minutes, until tender. Serve in bowls with the soup, garnished with fresh herbs.
