Core apples, starting at stem end, without cutting through opposite end. Scoop out apple pulp to enlarge opening to 2 inches. Chop pulp, and set aside.
Place each apple in a 7-inch square of aluminum foil.
Stir together chopped apple pulp, 2 tablespoons almonds, sweet potato, and next 5 ingredients. Spoon filling evenly into apples; top with remaining 1 tablespoon almonds. Pull foil up around sides of apples, and place apples in an 11- x 7-inch baking dish.
Bake at 350° for 45 minutes or until tender.
