The strings of celery with the stickiness of peanut butter leads me to lots of questions.
Cut a stalk of celery into three or four pieces, spread peanut butter inside the celery, and arrange a few raisins on top of the peanut butter.
These three foods combined provide a good balance of carbs, protein, and fat. Just be sure to buy peanut butter without added sugar or vegetable oils.
