Bosna is an Austrian sandwich originating from Salzburg. It consists of an elongated white bread bun that's filled with a bratwurst sausage, onions, parsley, ketchup, mustard, and curry powder. Bosna with one sausage is called Kleine Bosna, while the version with two sausages is known as Große Bosna.

It is believed that the sandwich was invented in 1949 by a Bulgarian named Zanko Todoroff. This sandwich can be easily found at many street vendors in Austria.
