I find that my son does not eat enough fruit, so I make this little dessert. It's colourful, and the cookies and marshmallows add just enough sweetness to make it irresistible.
It's best to add the marshmallow and chocolate biscuit immediately before serving. Otherwise, they get mushy.
Instead of one large marshmallow, toss a small handful of mini marshmallows into the salad before serving.
