Sweet, Sweet Potato
Basically, all you have to do is bake a sweet potato as you would normally bake them. Once baked, cut the potato down the middle, but not all the way through, and spoon some mini marshmallows down the center while the potato is still hot. Then sprinkle a little nutmeg or pumpkin-pie spice on top of the marshmallows and enjoy!
If you're counting points, a large sweet potato is 3 points, and 2 tablespoons mini marshmallows are not even 1 point (.5 to be exact).
