Notes
Do not substitute whipped cream for the whipped topping. It will not be able to hold all of the other ingredients without deflating.You can use regular 10 regular marshmallows instead of mini marshmallows. Cut them into quarters with kitchen shears before adding to the salad.You can use the reserved pineapple juice in a fruit salad or a smoothie. Or toss it with sliced apples to prevent them from turning brown.Make it ahead: you can prepare the salad up to 24 hours in advance. Refrigerate until ready to serve.
