If you are part of an org in the US (PSL, DSA, FRSO et al), I think this is just the sort of thing you should be helping to organize for in your community.
Are any of you part of orgs or know orgs that are doing this work? If so can you mention them here?
My kids’ school sent out a list of food pantries and soup kitchens. Almost all run by churches. Do with this information what you will.
