Mark's Peanut Butter "Mousse"

 0% Fage Greek yogurt with some natural creamy peanut butter swirled in and 1 packet of splenda (or preferred sweetner).  Put in freezer for about 10-15 and stir it up. It's like a decadent peanut butter mousse. Sprinkle a few almonds or walnuts on if you'd like.  Tastes like peanut butter pie! :)"
