What lunches do you remember from school?

In elementary school they had this hamburger gravy that was SO GOOD! I’d be trading food like crazy to get more.
In middle school Mom sent me with sack lunches, usually PB&honey and chocolate milk in a thermos….the kind that broke glass inside if you dropped it.
I remember using oranges to make funny mouth things.
That’s pretty much all I remember. I was always hungry when lunch rolled around.
Also they served us on large plastic trays that they washed and reused. Today they use styrofoam which they throw away. >_<
