Puree frozen pineapple in a blender. It works best if it is about halfway thawed. To that, add the ice cream, lime juice, lemon juice, and half (6oz) of the pineapple juice. Blend together until it is well mixed.
Freeze the mixture for about 2 hours to set up.
Scoop into glasses or bowls and pour the remaining pineapple juice over each serving.
We found it made about 3 servings, but you can easily double or cut the recipe in half. Dream of Disneyland and enjoy!
