To the US GenZ: Did your K-12 school years have freshly-made lunches? Or was it all canned/cold/premade? What changes would you have liked to see?

I'm an Asian immigrant who grew up in the US. It seems that the school lunches in the US are mostly premade and reheated, with the school kitchens and staff being poorly equipped to actually cook food from scratch. But due to my background, I know that in east Asia, most schools have both the equipment and staff to cook most of the food from scratch or close to it. I feel like this must have been the case in the US as well, a long time ago. What changed? And what would you like to change about it now?

Personally, I would love to see freshly-cooked meals in schools. But making food for many is a massive operation that requires significantly more staff, and the schools are not equipped with kitchens capable of making food from scratch. Reheating premade food prepared by the lowest bidder is much more economical, which is why it's common practice in the US. I didn't have much gripes about the school lunches growing up, but my little sister says it's gotten so bad now that she has taken to making and packing her own lunch.
