Put a lighter spin on meatloaf with ground turkey that borrows delicious flavors of fall from apple, sage, ginger, and maple syrup.
Preheat oven to 375 degrees. Process bread in a food processor until coarse crumbs form. (You should have about 2 cups.) Transfer to a large bowl. Put ginger and garlic in the food processor; process until chopped. Add onion and chopped apple; puree. Transfer to the bowl with breadcrumbs. Add eggs, turkey, sage, salt, and pepper. Mix thoroughly with your hands.
Transfer to a 12 3/4-by-4 1/2-by-3 1/4-inch terrine mold. Peel and core remaining apple. Cut into 1/8-inch-thick rings. Arrange apples on top of loaf. Bake until bubbling around corners, about 30 minutes. Cover, and bake until apples are soft and translucent, about 15 minutes. Uncover; brush with maple syrup. Bake until loaf is no longer pink in center, about 10 minutes. Let stand 15 minutes before serving.
