At Baology, a Center City lunch spot serving modern Taiwanese food, diners can sample potstickers, bao buns, and ruen bing, Taiwan's version of a mini-burrito.
Ruen bing is probably the most authentic Taiwanese item on the menu, co-owner Judy Ni said: fresh vegetables and a choice of four proteins curled into thin, flour-based wraps. Diners can choose from crispy beef, shredded pork, seared shrimp, or the vegetarian version, made with bean curd. The fillings give each ruen bing a different character; the beef tastes rich and caramelized; the bean curd is spiced.
Those fillings are rolled up in the wrappers with sauteed cabbage, carrots, mushrooms, and garlic chives, and dressed with peanut powder and hoisin sauce that add sweet and savory flavors.
"It's meant to be portable, hand-holdable," Ni said of the snack, which she said is a mainstay in market stalls and is even making its way to some high-end restaurant menus. It's also a popular dish for family mealtimes, she said, because it can be customized with so many different fillings.
