A delicious "salad" with unique ingredients that come together perfectly! The best at potlucks or BBQ's!
In a large bowl, mix together the pudding mix and the buttermilk. It will be thick. (You can use a whisk or a hand-held mixer.)
Add in the pineapple and mandarin oranges and stir well.
Chill until ready to serve.
Crush cookies and mix in just before serving. Reserve a few for garnish.
