"Green Glop" ~ r

I'm sure this dish has a more sophisticated name, but in our family it is referred to as "Green Glop" or "Body Filler".  Despite the silly names we've given it, this salad/dessert/whatever is delicious and a Must Have at family gatherings.

1 large Cool Whip
1 instant pistachio pudding mix
1 19 oz. crushed pineapple
2 cups mini marshmallows

Mix together and chill before serving.
