In this recipe from "Martha Stewart’s Dinner at Home," the pasta is topped with Turkey and Pancetta Meatballs, but it also makes a delicious starter or light main course on its own.   Pair with a light-bodied red wine with some earthiness, such as Dolcetto d'Alba or barbera, or a crisp white wine from Friuli, such as pinot grigio or Tocai Friulano. And serve with Salad with Fresh Mozzarella and Coffee Ice Cream Affogato for a tasty spring menu. Fresh fava beans are found at specialty produce stores and farmers' markets. If you can't find fresh favas, look for frozen (shelled) ones at supermarkets and natural-food stores; defrost according to package instructions.
