I do about the same thing, althought instead of no sugar filling I use a can of cherries and a can of cherry pie filling. You're right, it isn't so sweet...and basically we are doing the same thing. Cherry pie is my very favorite dessert! Although, recently I've been on a kick making a pie called "bumbleberry." Strawberries, blue berries, raspberries, plus a tart apple makes the filling. It's yummy. This is strawberry festival weekend in Southern Indiana.....supposed to be a good year for strawberries!
