Making food in public for homeless people runs afoul of food safety laws

Or, further, taking waste food to distribute to homeless is also against the rules. I used to work at a pizza hut express, we would have small personal pan pizzas in a ready to go area for like 15-20 min then throw them away if they were unsold. At the end of the day you'd have a trash can full of personal pan pizzas that were honestly fine to eat. You'd get fired for doing anything with them though.
