Low Fat Tiramisu

This dessert is so good and so high in calories. Being on Weight Watchers, this dessert was always off limits. I ran across this dessert in the Tribune a while back and it claims it is Low Fat. Whether it is or not, this is one dessert I would love to have on my Weight Watcher's diet. If anyone can cut this down (calorie wise), or if you have a recipe for Low Fat Tiramisu,please let me know.
