Pickled herring with boiled potatoes and green onion

This dish is really popular all over Ukraine, Poland, Russia. It usually served as an appetizer with a range of  salads, cold cuts and  aperitifs (drinks)

The pickled herring is sold in Eastern European stores.

All I do is add a little bit of sunflower oil over the fish (unless it is all ready with oil in a package) and add some green onions over the herring and boiled potatoes
