These stuffed dumplings derived their name from the Polish word for filled dumpling: pieróg. This former peasant food evolved into one of Poland's favorite dishes. Every family has their own version of pierogi filling, and the ingredients that can be used are limited only by the imagination of the chef.

Pierogi can be sweet, savory, or spicy, and the most common fillings include cheese, onions, ground meat, mushrooms, potatoes, and sauerkraut. The sweet versions commonly include various berries, such as strawberries or blueberries. Traditionally, these dumplings are served as the 12th course of a traditional Polish Christmas Eve dinner. 

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. 

Bułka z pieczarkami is an authentic Polish mushroom roll consisting of a bread roll that is stuffed with mushrooms and onions. Other optional ingredients include grated cheese, sausages, or heavy cream. The rolls are served hot and crunchy, topped with ketchup, mustard, or a combination of both.

Although they are somewhat overshadowed by more popular street food fare such as burgers and hot dogs, mushroom rolls are still a typical street food item in Poland, sold at numerous food kiosks and street stalls across the country.

Knysza is a thick, semicircular bread roll filled with various ingredients, drenched in garlic sauce, mayonnaise sauce, or hot sauce, and topped with roasted onions. A typical Polish street food, it is found in a vegetarian, meat, and cheese version.

Vegetarian knysza is slathered with sauce and filled with vegetables, usually cabbage, cucumbers, tomatoes, lettuce, canned corn, pickled cucumbers, and the mandatory roasted onions. The meat version is the same as the vegetarian with the addition of sausages, pork or chicken chops, salmon, or tuna fish, while the cheese version consists of vegetarian knysza with grated cheese.
