NO PASSPORT REQUIRED 9 p.m. on PBS (check local listings). The chef and restaurateur Marcus Samuelsson highlights immigrants’ culinary contributions to American cities in this six-part series. His first stop is the so-called Arab capital of North America: Dearborn, Mich. He learns how to prepare a traditional Iraqi bread, dines with a family of Syrian refugees and cooks alongside a Lebanese-American pastry chef. An immigrant himself, Mr. Samuelsson argues that immigrants not only diversify the country but also enhance its flavor profile: “What would America be without all the immigrants? Not as delicious! Not as tasty!”
