Pistachio Salad

My friend, Eni, posted this on her blog a while back.  I have been dying to make it and now I finally have!:)  It is sooo creamy, delicious and super easy to make.
-16 oz whipped topping
-1 small package pistachio pudding (dry)
-16 oz crushed pineapple, drained
-2 cups mini marshmallows
-1 cup shredded coconut
-1/2 cup chopped walnuts
In a large bowl, mix whipped topping and pudding.  When mixed well, add remaining ingredients.  Enjoy!
