Turn the heat down to medium and let simmer for 10 minutes. Add the cabbage and simmer for a further 5 minutes. Add the chopped parsley last and serve hot in deep bowls with some buttered bread.
This is actually a cabbage soup with the unpronounceable name “Shchi”. And there was a proverb - щи да каша - пища наша (Shchi and porridge is our food). And that's it.
