Here is a Weight Watchers recipie that is an old fav of mine...It is very simple (which i like!) but is really tasty considering its low in calories and fat. I've even made the filling and just eaten it out of the bowl, with it never making it to the crust lol...and sometimes I top the pie with extra whip cream. Give it a try! :)
