I heard a story once on NPR about school lunches in France - made with locally purchased fresh ingredients - I want to eat school lunches there!
I'm not sure that rural districts can do now what was done when I was in school - the local game warden would donate fresh road kill or illegally harvested game. I remember looking through the slats into the kitchen in my HS to see a deer on the floor. Venison chili was on the day's menu.
That's both kind of gross and kind of awesome.
Ours were $2.50 or $2.75 when I graduated. I think the price has gone up since. Fries were a staple. And they were handed out...rather generously.
