Slice the leftover meats into bite-sized pieces and place in a large, non-reactive bowl with the frisee and radicchio. Toss well with 2 tablespoons of the vinegar, oil and salt and pepper. Divide evenly among 6 chilled dinner plates, top with shaved curls of Parmigiano, drizzle remaining vinegar over and serve.
