Absolutely. Yes. The local part goes a long ways

Some hopeful example :

Quebec hospitals started cooking all their food internally on the same budget.

More and more French municipalities stopped their frozen food subscription to hire a handful of cooks and gardeners with a similar budgets. ( those are minimum wages jobs than can be sourced locally )

To conclude : human have been cooking food in batch for quiet a while. That what I mean when I say « we forgot » : some communal facilities like school don’t even have kitchen anymore.
