These two things, popcorn and hot chocolate, have become regular afternoon snacks for us this winter.
I have been forgoing the air popper and instead making each person their own individual bags. I just cover the bottom of a brown lunch sack with popcorn and fold the top down twice, put it in the microwave and hit the popcorn button. I don't actually let it go as long as the microwave wants to nuke it for. Burnt popcorn is the worst.
I spray a little spray butter in there, salt it and then shake and Voila! A simple afternoon snack.
