4 sweet potatoes (8 ounces each), unpeeled 
1 tablespoon reduced-calorie margarine 
1/2 teaspoon brown sugar substitute 
1/4 teaspoon ground cinnamon 
1/4 teaspoon allspice 
1/4 teaspoon nutmeg 
1 can (8 ounces) crushed pineapple, canned in juice 
2 tablespoons chopped walnuts 
1 cup miniature marshmallows 
 
Preheat oven to 400˚F. Wrap each sweet potato in foil, place on oven rack, and bake for one hour, or until tender when pierced with a fork. Remove from oven and allow to cool 15 minutes. Cut each potato in half lengthwise and carefully scoop flesh into a bowl, leaving shells intact with 1/8–1/4 inch of flesh. Place shells in a baking dish and set aside. Using an electric mixer, mash flesh until smooth. Mix in margarine, brown sugar substitute, and spices. Drain pineapple well in a sieve, forcing out extra liquid with the back of a spoon. Stir drained pineapple into mashed sweet potatoes. Spoon filling into shells; sprinkle with walnuts and press on marshmallows. Return to the oven for 8–10 minutes, or until marshmallows are lightly toasted and potato is heated through.
