This is a transition salad because it uses produce you can find from early fall through the darkest depths of winter.
Note: When crisping the pancetta, reserve 1 tablespoon for the dressing if you want a smokier dressing flavor; otherwise, use olive oil. To make dicing the pancetta easier, place the pancetta in the freezer until thoroughly chilled, about 10 to 15 minutes and then use a serrated knife to cut it.
