You're food savvy. You've heard of the dirty dozen. You try to buy organic. Me too. The winter time is coming to most of us, so perhaps you've just cranked open a couple of cans of tomatoes, added some beef, and you have a pot of warm chili simmering on the stove. Maybe you are baking up some potatoes to go with it. While you wait you pop up some microwave popcorn and snuggle up to watch a movie.
