In a meat-loving city like St. Louis, carnivores have plenty of dining options. But Balkan Treat Box stands out for its sausage-stuffed sandwich priced at a steal. The cevapi sandwich ($10) is a top seller at this food truck known for its Bosnian and Turkish eats. To make it, they grill more than half a pound of mini beef sausages over charcoal, then stuff the mound of meat into a freshly baked somun pita with onions and a Bosnian cream cheese called kajmak. Take it from us, you may need a post-meal nap after tackling this bargain behemoth.
