Fluffy Pistachio Pudding & Pineapple Delight

1. In a large mixing bowl, combine the pistachio pudding mix and the undrained crushed pineapple. Stir until the pudding mix is fully dissolved and the mixture thickens slightly.
2. Gently fold in the whipped topping until fully incorporated.
3. If using, fold in the chopped pistachios and mini marshmallows for added texture.
4. Transfer the mixture to a serving dish or individual cups. Cover and refrigerate for at least 1 hour to allow the flavors to meld and the dessert to set.
5. Before serving, garnish with extra chopped pistachios for a decorative and crunchy finish.

Serve chilled and enjoy this refreshing, fluffy dessert!
