Preparation Preheat oven to 400°F. On foil-lined baking sheet, toss potato slices with 3 tablespoons melted butter, 1 teaspoon salt, and 1/2 teaspoon pepper. Bake until cooked through and slightly caramelized, about 20 minutes. Keep warm. In heavy medium skillet over moderate heat, melt 3 tablespoons butter. Add apples and sauté until tender and golden brown, about 15 minutes. Keep warm. In heavy large pot over moderate heat, combine remaining 2 tablespoons butter and 3 tablespoons water. Add greens and sauté, stirring occasionally, until wilted, about 5 minutes. Lower heat to moderately low and add sweet potatoes and apples. Continue cooking, stirring occasionally, until warmed through, 3 to 4 minutes. Stir in parsley, remaining 2 teaspoons salt, and 1 1/2 teaspoons pepper. Serve hot.
