Roasted Fennel with Parmigiano

Fennel is crisp when raw and tastes of licorice. When roasted, it mellows in flavor but maintains a nice firmness, which is complemented here with just a simple dusting of Parmigiano. The key to preventing Parimigiano from drying out in the refrigerator? Don't buy too large a piece: The smaller the chunk, the faster it is used, the fresher it stays.
