Tyurya

Chop the parsley not too finely. Cut the onion into half rings. You can cut a whole onion or do without onion at all — it's a matter of taste.

Add sauerkraut, onion, parsley, and bread to the cold kvass - you can cut the bread into medium cubes or tear it by hand. Stale bread can also be used: it's a way to prevent it from going to waste.

Mix and pour into plates.
