Of course building a system to distribute all that food would be a logistic nightmare. A lot of wasted food is perishable or VERY perishable.

Better to take it to neighborhood feeding centers, prepare it, and give it away to anybody who walks in the door. Minimize waste and minimize transport. Very little administration required because you just give it to anybody, no cards, no paperwork, no ID. Just folks to move it and cook it. I bet people would do that for some cash on top of their UBI.

Another advantage of such community feeding is that low income housing would not require kitchens.
