Finely chop fresh dill and green onions. To improve the taste of the dish, chopped greens need to be grated until juice appears.
Stir the chopped food in a common bowl and season with salt. Then put the salad mass on a portioned plate, add 0.5 teaspoons of grated horseradish, 1 tablespoon of sour cream if desired. Pour the desired amount of kvass. For taste, you can add some table mustard to okroshka. Mix everything well.
Sprinkle okroshka on top with fresh herbs. Serve okroshka on cold kvass.
