Cook the bacon in a nonstick skillet over medium heat until crisp. Remove the bacon from the pan; crumble. Discard the drippings.
Add the orange juice, brandy, vinegar, and honey to the pan; cook over medium-low heat for 5 minutes or until reduced to about 2 tablespoons. Stir in the bacon, salt, and pepper.
ASSEMBLE THE SALAD:
In a medium bowl, combine the water and lemon juice. Add the apple; toss to coat. Remove the apple from the bowl with a slotted spoon; place in a large bowl. Add the spinach, onion, and mango to the apple. Drizzle with the vinaigrette, and toss gently to coat.
Arrange about 2¼ cups of the salad on each of 2 plates; top each serving with 1½ teaspoons walnuts and half the raspberries. Serve immediately.
Notes
I like to use center-cut slices of bacon because it has more meat and less fat.
If you're preparing this as a Gluten Free recipe, be sure to use a brand of bacon that is designated as GF.
