If you're so poor that you can't afford food, what are the chances that you have access, time, and ability to turn ingredients into meals every time you need to eat.

I'm totally fine with a person on SNAP using it to get a hot or prepared meal if that's what they need. We have already decided to allocate the resource to them for the purpose of buying food, why does it matter if they spend it on a premade sandwich instead of a frozen burrito.
