It sounds like there were a few problems identified.
* Against the rules to hand them out to non-students (even after some priority window)
* Operating in an unusual context where relative load is highly unpredictable
* No system of reservation to try to forecast load
There's also a bunch of data that's absent, like any potential causes for the variable load. Plausibly it might have been weather related, or related to families participating in a cultural event that's special even if they were celebrating in quarantine at home.
The first is food regulation and safety law; the same applies to restaurants who serve buffet style as well.
The second isn't going away. Attendance is spotty at best in underperforming schools, in particular the ones that need free lunch the most. Many kids also won't eat some foods. The amount of waste just gets shifted from "too much prepared" to "not enough served food was eaten".
The third is just an attempt to solve the second, but if there was a system of reservation in place, it would still be part of the problem- after all, what we're trying to solve is that parents aren't utilizing the already available free lunch programs because going through the means testing is too much effort for them.

This, food waste is built into the system. It'd be nice if it wasn't but every restaurant and cafeteria throws away just as much food as they sell, most people just don't realize it because they've never worked in food service.
