One of Poland's favorite fast foods is this unique open-faced sandwich. The scrumptious Polish zapiekanka is made with a plain white baguette cut lengthwise, topped with a variety of tasty ingredients and a generous heaping of grated semi-hard cheese, and grilled under a broiler.
Hailing back to the 1970s, this snack originated at a time when even the most basic of ingredients were hard to come by in communist Poland, and people had to think of how to make the best use of whatever they had available. The original zapiekanka was made with sautéed mushrooms and cheese, but with time, a variety of other ingredients such as meat, bacon, sausages, or even feta cheese, olives, and pineapple started to become customary toppings for these crusty warm sandwiches.
