File this under the what-will-they-think-of next department: the Green Bag Lunch.

For $5, the Green Bag Lunch company will deliver to your child's school a healthy lunch, packed in recyclable and biodegradable materials. You order the lunch online -- choices include a main dish, such as a turkey sandwich, two veggie/fruit sides, and a dessert. Food arrives in coolers before lunchtime.

According to a Chicago Tribune story, Green Bag Lunch has taken off in Chicago. And they hope to get the price down to $3 to make it more palatable for parents, though they say it will cost about $4 if you make the lunch at home yourself. (excuse me, but a box of mac and cheese is, like, two or three dollars, and in my house that is lunch for about three days. Throw in a piece of fruit and a cheese stick and I still think it won't top $2.)

But so many questions remain. Where do they deliver? Does every school participate? What is the reaction of the school administrators about having to take custody of the lunches? The link from treehugger.com doesn't answer a lot of these issues. But for all of us who spend a lot of time preparing our kids' lunches, the idea is at least intriguing.
