Chop half of the nuts of your choice and leave the other half for garnish.

Place the crushed pineapples in a bowl and add the pistachio Jell-O instant pudding mix. Mix until well combined.

Add the miniature marshmallows and chopped nuts. Mix with a spatula until well combined.

Now add the Cool Whip to the pudding mixture and gently fold it into the mixture with a spatula.

Transfer the mixture into glasses and chill for at least 60 minutes in the refrigerator. Once chilled, serve the Watergate salad cold. Enjoy!
