A no-bake pineapple cheesecake with a minimum of ingredients you'll have to go out and buy. Just make sure when you drain the pineapple, you drain it very, very well. If not, the cheesecake will never really set up properly. It'll still taste great, but it'll be messy. Weight Watchers points information is as follows: 1 slice (1/6th of cheesecake) has 435 calories, 25 grams of fat, and 1 gram of fiber. You could cut smaller slices and cut down on the points. You could also use light cream cheese to save points further.
