Should be hot dinners during the winter.
My DC(6) is in year1 at a school with a diverse intake and an above average % of children eligible for free school meals. Although in reception,y1&2 all the kids are offered free school meals anyway.
At the moment they are provided with a ham or cheese roll, biscuit and a slice of apple. Sometimes there are carrot sticks too. That seems fine for the summer, if a bit boring. But "in my day!" there was always a hot meal option. Especially important for the kids who may not get one at home.
Even with c19 many establishments and institutions are able to run a kitchen serving hot meals.
What's happening re:food at your DC's school at the moment?
