Here is one of my favorite WW recipe's. It's easy and really good.
PINEAPPLE ANGEL FOOD CAKE
1 angel food cake mix
1 large can crushed pineapple in it's own juice
one carton no-fat cool whip
Mix angel food cake with one can of pineapple (add nothing else) Mix with spoon or spatula. Spray a 9x13" pan with non stick spray. Bake @ 350 degrees for 25 minutes or until the cake is done. Let it cool and frost with cool whip. Cut it into 20 pieces and it's 2 points per serving. Bigger pieces more points! (It's also good with strawberries on top)
