It's a traditional sausage from Poland made of minced meat.It's
called kiełbasa. There are many types of Polish sausages,the most
common are:sucha krakowska(thick and smoked),kabanos
(thin,air-dried and flavoured with caraway) and wiejska
[vieyska].
You can buy Polish sausage in the US but it's doesn't taste like
the genuine kiełbasa.
