1. Preheat oven to 350°. Bake walnuts in a single layer in a shallow pan 6 to 8 minutes or until toasted and fragrant, stirring after 5 minutes. Cool completely (about 20 minutes).
2. Stir together walnuts and next 3 ingredients. Spread on 1 side of each bread slice. Spread fig preserves on half of bread slices; top with remaining bread slices, cheese sides down. Chill sandwiches in airtight zip-top plastic bags up to 24 hours, if desired. Cut crusts from sandwiches. Cut each sandwich into 8 pieces.
Note: For testing purposes only, we used Saga blue cheese and Pepperidge Farm Whole Grain 15 Grain Bread.
