I don't really know why some salads are called salads instead of desserts. But whatever, my kids really like this one, and it makes me feel better to think they are eating "salad."
1 family size container of strawberry yogurt. (The 2 pounder.)
2 cups strawberries, cut up.
1 small container whipped topping
1/2 cup marshmallows
Just mix it all up, and you're good to go. (Put it in the fridge if you have leftovers.)
This one is also good with raspberries and raspberry yogurt instead of the strawberries.
