This healthy snack is so simple to make that your kids can even do it themselves - so there's no need to go hungry on your adventures!
Spread one tablespoon of peanut butter on each half celery stalk then push sultanas into the top. It's that easy!
If you've got a bit of a sweet tooth, you could always swap the sultanas for chocolate chips and replace the celery with a banana for slow release of energy.
