gyro

A gyro is a Greek dish consisting of meat cooked on a vertical rotisserie, typically served wrapped or stuffed in pita bread along with ingredients such as tomato, onion, and tzatziki sauce. Imagine a large, rotating cone of seasoned meat being thinly shaved off by a chef to create a warm, savory handheld meal. The word is commonly used in casual settings when discussing fast food or Greek cuisine. Note that while the Greek pronunciation often sounds like "yee-ro," it is very common in American English to hear it pronounced with a hard "g" sound as in "guy-ro." It is almost exclusively used to refer to the food item itself.
