To follow the question about self-scheduling appointment apps, is there an app out there that allows food pantry visitors to choose foods they want to pick up?

We would also be interested in same. A number of food "rescue" apps, it seems, but have yet to find any that deal with the distribution of food to recipients.

 can you explain a bit about the overall process you’re trying to improve?

 Would this be something like a take-out menu at a restaurant?  Or something more simple such as a short online survey where  a person could enter their name/date/time and then  pick some options from a list?

Something as simple as Google Forms might be able to handle the latter.
