This salad is perfect for a post-election dinner. Bitter radicchio and endives are tossed with walnuts and crumbled blue cheese. The dressing is made with grapes and sesame oil, which Jefferson made himself in replacement of olive oil. Serve this as an appetizer for a dinner party, or you can also turn it into an hors d'oeuvre by hollowing out the center of the pear, filling it with cheese, and garnishing with julienned radicchio.
