Penne with Cauliflower and Leeks
This extremely flexible recipe can be adapted to include several different kinds of seasonal vegetables. In winter and spring, Salvatore Denaro might make it with Umbria's small, violet-colored artichokes; in the fall he prefers cauliflower or broccoli. A pretty alternative is pasta con cavolfiore e broccoli siciliani, with equal parts cauliflower and broccoli; the dish is also terrific made with leeks alone.
