It's easy to get stuck in a rut with sandwich or treat ideas. These are a fun and healthy snack or lunchbox idea. I'm using peanut butter in this version, but you can use any nut butter - my favourite is almond. Also try different toppings like nuts, dried fruit, or coconut.
To keep apple slices from going brown soak them briefly in some cold water with a dash of lemon juice. Use a cutter to make heart or star shaped centres and try out different toppings and spreads.
