I had my son do every step of preparing this snack, starting from washing his hands. Then washing the celery.
He then used a sharp knife to cut them into manageable pieces. I showed him which parts taste good, and what should be tossed in the compost.
Little sister got to join in the fun, and helped put the ants on the peanut butter logs, after big brother neatly spreader the peanut butter.
Success! The kids ate them, and actually liked them. Seems they'll eat their veggies if they make the snack themselves.
And the cook is pleased too. I even got them to clean up the mess too. Cooking apparently is fantastic fun. :)
