Great idea- sliced apples with caramel, marshmellow, chocolate and peanuts!
Instead of melting your own caramels, use ice cream caramel topping and for the marshmellow topping, use fluff that has been melted.
Strawberry Nachos - actually made these tonight and definitely will be adding them to my rotation! Would be pretty easy to prepare most elements ahead of time and assemble quickly. (the baked cinnamon chips alone are a must-have!)
