For snacks, what about home made popcorn; roasted pumpkins or sunflower seeds; baby carrots, cherry tomatoes, celery sticks, etc with dip; dried fruits and nuts; home made cocoa or coconut chia pudding (I saw the recipe somewhere on internet), celery sticks with peanut butter; edamame with salt and maybe lemon. Even we are not gluten free, these are some of the gluten free snacks I have served dck and my family. I will be making the cocoa chia pudding soon. It sounds good.
