Truck Stop: Chez Yasmine

The man: Jihed Chehimi, probably the only food-truck owner in the world with a doctorate in viral immunology, serves up healthy global dishes with a smile. Make sure you smile back, because he'll probably snap your photo for the Chez Yasmine Facebook page.

Born in Tunisia, he opened the truck in 2012 when he needed a change of pace. "I was basically burned out," said Chehimi, whose tinted sunglasses give off a Hunter S. Thompson vibe. The truck is named after his daughter.

The menu: Well, it's huge. Be ready to read some fine print, due to the detailed descriptions.

The sandwiches are named after his regular customers, such as the "Nick's Addiction" tuna banh mi ($6) and "Alyssa & Claire: Menage a Trois Grilled Cheese & Soup" ($7).

There are way too many items to list them all here, but we enjoyed "Le Hipstere" chicken banh mi ($6), which is better than some of the banh mi we've found in Chinatown, and "Maria and Ally's" chicken couscous ($8), a full meal.

Leftovers! "It's a lot of couscous," Chehimi said. "We're always thinking that the student might keep some for later." That's what we did. Make sure to ask for harissa sauce. Way better than sriracha.

Bonus: Become a repeat customer and you might find your name on the menu. "The sandwiches are named after customers, and the customers become friends," Chehimi said.

Where: Small cart located around 37th and Spruce, on the University of Pennsylvania campus.

Online: Find it on Facebook at "Chez Yasmine Truck" or go to chezyasmine.org.
