In Poland, where I live, a certain fish dish became very popular not so very long ago. It's called "ryba po grecku" which essentially translates to "Greek-style fish". The recipe is not particularly complicated, and I personally find it very tasty, but I was wondering if it is actually something originating from the Greek cuisine, or perhaps somewhere else, and hence I want to ask if you ever came across something similar.
The basic idea is to get some fish filet (most popular choices include hake, pollock and common sole), cut it into middle-sized pieces which you then sprinke with lemon, salt and pepper, roll them in flour and fry on both sides in a pan. In a separate pan, chopped onion is fried until it gets soft, at which point grated carrots (sometimes also parsley, celery, leek) are added, and this is braised (with water) until the vegetables are soft. Some tomato concantrate is mixed in and the mixture is flavored with salt, pepper and allspice to obtain a sort of paste with distinct, soft onion chunks. It is supposed to be quite thick, not liquid. The fried fish pieces are mixed with this paste and put in a fridge (it's said to best let it sit for approx 2 days) and the dish is served cold, like a salad.
