Koulouri Thessalonikis is a traditional street food staple and their national take on simit—a similar circular bread found in Turkey. In its simplest form, koulouri is made with wheat flour dough that is shaped into a ring before it is coated in sesame seeds and baked.
This Greek version is believed to have traveled with Greek refugees from Asia Minor who first settled in Thessaloniki, hence the name. The origin is still disputed between the two countries, but the Greeks have implemented this crunchy and filling snack in their national cuisine.
