I found this blog a while ago. A teacher eats lunch at school with the students every day, with photos.

One of the shocks of moving to the US, was the surprising lack of quality of food. Not just processed either, but fresh meat and vegetables, fruits. The first time I cooked Tyson chicken I thought it was bad because the amount of draining of liquid from the meat. I tossed it, and began again, and only then realized that was the way the meat was.
