Cookie Salad

Everyone has had this before but it's always a classic so I thought I would do it this month!

2 (3.4 oz) packages instant vanilla pudding mix
2 cups buttermilk
12 oz. frozen whipped topping, thawed
1 (20 oz) can pineapple chunks, drained
2 (11 oz) cans mandarin oranges, drained
1/2 (11.5 oz) package fudge striped cookies

Directions:
In a large, mix together the pudding mix and the buttermilk. Fold in the whipped topping. Mix in the pineapple chunks and mandarin oranges. Chill until ready to serve. Crush cookies and mix in just before serving.
