Before you yawn at the thought of eating a quesadilla — one of the most run-of-the-mill Mexican dishes around and, perhaps, the most frequently gringo-ized — we want you to think beyond the generic cheesy creation that's stuck in your head. Think of something more substantial, with a savory masa crust around chicken and cheese filling. Imagine the whole thing slathered in tomatillo sauce, piled with shredded lettuce and crumbles of cotija. And now think of sinking your teeth into that. It doesn't sound like a quesadilla at all, really, but it's just a regional Mexican specialty. Like so many other tasty dishes at Huauchinango, the quesadillas are cooked in the style of Puebla, in Central Mexico. Different is delicious, and Huauchinango is proof.
