Seoul Taco. Guerrilla Street Food. Frankly Sausages. The food truck that outshines the traditional brick-and-mortar competition is no longer a surprise. To this roster you can now add Balkan Treat Box, which chef-owner Loryn Feliciano-Nalic first announced in 2015 but didn’t roll into regular service until this year. Feliciano-Nalic installed a wood-burning oven in her truck, and in this she bakes the Turkish flatbread called pide (topped with ground beef and piknik cheese) and the somun bread for plump Bosnian cevapi and a juicy chicken döner kebab. That’s essentially the entire menu, but the wood-fired breads are sublime, and those dishes are more than enough to recommend Balkan Treat Box — and to suggest, like the trucks listed above, the concept is bound for even bigger things.
