Cheap 'Produkt' Lunch Menu/food

Often while we are out walking here in Moscow, Russia, we find ourselves looking for these 'Produkt' stores.  Quite similar to a small, local, corner mart, they have the cheapest prices by far and a fair number of them have small kitchens inside (a few have larger kitchens offering up quite a wide-variety of foods).  On our last day in Moscow, after Arbat and before heading to the train stations, we stopped at this one for some simple grub.  Even added two 20 rouble coffees to the meal.  All that for pennies...can't be beat!
