I know what you think - can't possibly be edible. Believe me - it is beautiful. This is a Polish dish, a soup made of sour cucumbers, or pickles. You can buy a jar of them thinly sliced in Polish shops but if there is none in your area you can just slice pickles. I usually just make the soup from the vegetables and that's it, but you can throw a chicken stock cube in as well to make it more tasty if you want.
