Watergate salad is a nostalgic, creamy dessert that is as delicious as it is easy to prepare. This vibrant green dish, made with pistachio pudding mix, crushed pineapple, whipped topping, mini marshmallows, and chopped nuts, became a beloved staple at potlucks and holiday tables.
In a large mixing bowl, combine the instant pistachio pudding mix and the undrained can of crushed pineapple. Stir until the pudding mix has dissolved and the pineapple is evenly incorporated.
Gently fold in the whipped topping until fully blended.
Stir in the mini marshmallows and chopped nuts until evenly distributed throughout the salad.
Cover the bowl and refrigerate the salad for at least one hour, allowing the flavors to meld and the texture to firm up.
Before serving, garnish with maraschino cherries if desired.
