The ingredients are a few: cabbage, pickle cabbage/carrot mix, tomato paste, onions, potatoes and hachar, which I do not really know how to translate in English (հաճար).
One important reminder: wash the hachar in advance.
To be frank, my husband was not very happy about this soup, but I love anything, which has pickles inside.
This is how Wikipedia defines the soup
Krchik – soup made from sauerkraut, hulled wheat, potatoes, and tomato purée.[19]
When making the soup, I understood there is something common with Russian Shchi (simply because of too much cabbage in both) and when googling it here is what I saw: http://gotovlyu.com/en/recept/krchik.html
So, bon appetit!!!
