I made this for just two of us, but you could easily double it, or triple it, if you want!
8 oz. frozen pineapple chunks
2 cups vanilla ice cream
12 oz. pineapple juice
Thaw frozen pineapple about half way. Puree frozen pineapple in a blender. Add the ice cream to the pineapple puree along with about half of the pineapple juice. Blend together until it is well mixed. Freeze the mixture for about 2 hours to harden. Scoop into glasses or bowls and pour the remaining pineapple juice over each serving.
