1 (20 oz.) can of unsweetened pineapple
 1 (21 oz) can of either blueberry, apple, or cherry pie filling
 1 box of yellow cake mix
 Pam-type spray
 Preheat oven to 350 degrees. Spray 13 x 9 x 2 inch pan.
 Process pineapple juice and all until it is like crushed pineapple.
 Spread in baking pan. Top with choice of filling. Spread dry cake
 mix over the mixture. From a 6 inch distance, coat cake mix with
 Pam type spray until moist looking. Bake for 30 minutes or until top 
 is brown and filling bubbles on sides. The only fat is in the cake mix. 
 You could reduce the fat more by using some of those Light mixes
