A light, creamy, nutty, and fruity retro dessert made with pistachio pudding, Cool Whip, crushed pineapple, marshmallows, and walnuts. Quick, nostalgic, and always a crowd-pleaser!
For fun variations, stir in maraschino cherries, shredded coconut, or mini chocolate chips. Use red and green marshmallows for Christmas or pastel marshmallows for Easter. Best served fresh, but can be stored covered in the refrigerator for up to 3 days.
