To make; mix one 3.4 oz box of instant pistachio pudding mix with one 20 oz can of crushed pineapple (juice and fruit, do not drain).
Stir in 2 1/2 cups mini marshmellows.
Fold in one 8 oz container cool whip.
You may also add 1/2 cup chopped pecans, but my family prefers neutered desserts (nut less!).
Refrigerate for at least 3 hours or overnight. Delicious! Unless you're my picky nephew who doesn't eat cool whip!
