4 potatoes (chopped)
3-4 stalks green onions (chopped)
1 small bunch dill
2-3 radishes (optional)
8 cups kvass or buttermilk/ kefir/ diluted yogurt
salt
Instructions:
Boil eggs and potatoes until done. Cool and peel. Finely chop all solid ingredients. Mix and salt to taste.
Add the liquid and serve.
