IMO, its the kebab. Any kind of kebab. They sound great in theory. What's not to love about your favorite meats and vegetables grilled together in loving propinquity? Alas, once the kebab leaves the realm of my mind and my plate, and passes my lips, its allure vanishes. Oh, the first several bites are nice, but soon thereafter eating kebabs becomes an exercise in tedium.
Well, that's my nomination. What's yours?
