Wild rice, apples, and walnuts combine to make a dressing full of flavor and crunch.
Preheat oven to 400°F. Toss bread cubes with melted butter in a medium bowl. Spread on a baking sheet, and bake until crispy and lightly browned, 5 to 8 minutes.
Heat oil in a skillet over medium-high. Add celery and onion; cook, stirring occasionally, until tender, about 8 minutes. Add apples; cook, stirring occasionally, until apples are tender-crisp and browned, 5 to 7 minutes. Stir in toasted bread cubes, rice, walnuts, chopped parsley, chopped sage, lemon juice, salt, and pepper. Cook until heated through, about 3 minutes. Spoon onto a serving platter. Top with parsley leaves.
