So I managed to find a picture of those fried bun things filled with potato !! I used to buy at least 2, wolf one down before I got on the marshrutka, and stuff the other one in my pocket for later. I loved how even when you fish it out of your pocket all squashed, it still tastes sooo good. The first time I had these was when the mini bus took a quick stop, and we were soon swarmed by a group of young girls selling these on trays.
