To make croutons, preheat oven to 350 degrees. In a medium bowl, combine 2 cups bread cubes, 1 tablespoon duck fat and 1 teaspoon chopped fresh parsley. Season with salt and pepper and toss to coat. Spread in a single layer on a baking sheet and bake for 20 minutes or until golden brown and crispy, stirring halfway through. Let croutons cool completely before using.
