You need to look better;) http://www.zdrowazywnosc.lompart.pl/upload/products_en/soczewica-czerwona-350g-s.jpghttp://www.zdrowazywnosc.lompart.pl/upload/products_en/soczewica-zielona-350g-sa.jpgPlus, you can buy soczewica in the market by Hala Mirowska - there is one stall there with all kinds of groats, lentils and seeds. Good luck!
Thank you!I also found red and brown ones, it's true! But I am still surprised not to find green lentils, which are as common back in Switzerland as rice, or as kasza here. Maybe it is not a variety that is grown around here?
