Students congregate around the Yalla food truck, which offers kosher and halal food, at Duke University in Durham, North Carolina. DURHAM, N.C. (RNS) — The Yalla food truck serves food that meets the most stringent dietary needs of two constituencies: Jews and Muslims. “We want to push Jewish and Muslim students to get together,” said Rabbi Nossen Fellig, a Chabad leader on campus who came up with the food truck concept alongside a Muslim colleague, Abdullah Antepli, a professor of the practice of interfaith relations.
