Veggies are good snacks too! Our afternoon snack was sometimes ants on a log (celery with peanut butter to stick raisins on) or carrots (this was before baby carrots was a thing). Or pickles. And if my dad was around we would sometimes get sardines on crackers. 1 sardine is only 20-25 calories and has lots of good protein and oil. Just not the yucky oil packed ones, the water packed ones.
