I'm a big fan of Culinate, and they have a useful article about healthy snacks for the whole family.
Do you do all of these already? Popcorn fell off my radar while the kids were little, but I could bring that back now. I've never done the sweet potato halves as a snack, so I'll have to try that. Cups of pureed soups are awesome, I'm glad it's easing into autumn and I can start making soups every week. I love making bread and soup for meals a couple times a week.
