Carrot Raisin Salad (Lubys)

Got this off recipezaar.  While I love Lubys I never order carrot raisin salad...I only make it at home to use up carrots but I quite like it.  This was done this without pineapple and it's great!

1 cup crushed pineapple, drained
1 cup raisins, plumped

2In a large bowl, comine the shredded carrots, raisins and pineapple.
3In a small bowl, mix the mayonnaise and powdered sugar until well blended, pour over carrot mixture and toss lightly to coat.
4Cover and refrigerate at least 2 hours.
