Serwus is healthy and modern version of the traditional Zapiekanka stall, which served open baguettes topped with meat, vegetables, cheese and ketchup as a popular type of fast food.
Zapiekanka (derived from zapiekać – “to scorch”, “to roast”) is a Polish halved baguette or bread topped mainly with mushrooms and cheese, also ham or other types of meat, and vegetables. Beside some basic versions there are several recipes like: “zapiekanka na ostro” (spicy Zapiekanka) and “zapiekanka z mięsem” (Zapiekanka with meat). They are usually placed in an oven until the cheese melts and the baguette or bread is crispy. It is served scalloped and usually topped with dressings, usually ketchup. Some variants include extra ingredients like onion or paprika, rarely chives. It’s a very popular fast food in Poland.
