Like most of you, I relish Thanksgiving leftovers. Stuffing, mashed potatoes, and turkey legs all possess a greater depth of flavor the next day. But white meat turkey always seems to taste worse the following morning. In my mind, consuming leftover turkey breast is up there with finishing day-old fish. To help matters, I decided to try a regional dish I've always wanted to make: the legendary Kentucky Hot Brown. This warm sandwich, created at the Brown Hotel in 1926, is an open-faced wonder of roasted turkey, bacon, and tomatoes on fat toast, drizzled with luscious Mornay sauce. Nearly a century later, there are many variations, but I returned to the original, a move I don't regret. I love how the creamy, nutty Pecorino cheese sauce offsets the lean tone of turkey breast.
