1. Preheat oven to 350º. Bake walnuts in a single layer in a shallow pan 5 to 7 minutes or until lightly toasted and fragrant.
2. Toss diced apples with lemon juice in a medium bowl; add walnuts, celery, raisins, and 1/2 cup vinaigrette, stirring to coat.
3. Divide greens among 12 salad plates; place 1 Savory Blue Cheesecake over greens on each plate. Spoon about 1/2 cup apple mixture over each cheesecake. Serve with remaining vinaigrette.
Note: For testing purposes only, we used Marie's Blue Cheese Vinaigrette.
