I have volunteered with Food Not Bombs in my city for six years. Many cities have their own branches. Food Not Bombs serves free vegan meals. As much as possible this food comes from food waste rescue. Many locations also distribute clothing, groceries, and hygiene products.
I volunteer in Kansas City, but like I said there are branches in most cities. I’ve visited groups in DC, Atlanta, Minneapolis, and Chicago. Here is a map, but I admit it is not up to date there are many inactive groups still listed on there. http://foodnotbombs.net/info/locations/
