I actually have found memories of my infants school lunches but then we didn't have much at home and school lunch was our only cooked meal. I know now looking back that my mum was skipping meals too feed us.
My favourite was steak and kidney pudding because all the other kids hated kidney so I'd swap my steak (which was stringy) for their kidney. On a table of 6 or 8, it meant I got more kidney than they did steak. I don't remember the vegetables being up to much though. We also got free school milk.
I'm trying to think when I started there, I guess it must have been 76 or 77, but none was a village school, not a city school, so it may have been different.
