I'll second the idea about food pantry/whatevers. Local soup kitchens (do they still call them that) are always willing to take any volunteer that comes their way, is a great way to socialize with other people, and no one's going to judge you. If you're not so happy with the idea of interacting with random people, working behind the scenes at a food bank type location is still volunteering, but is more about showing up at a warehouse somewhere and unpacking large boxes of bulk foods and then repacking them into smaller packages with a set variety of foods inside (I suppose this depends on the specifics of the work, but this is what I did many years ago).
These are pretty easy volunteer spots to get, wont require any time consuming checks, and they're always willing to take more people. Often, when working in the volunteer food industry (is that an industry?), part of the deal is that you can get a portion of the food box/whatever as "payment" for your help. So X hours of helping load boxes of food for others, and you get a box of food for your own household (and if working at a place that serves food, you're typically going to be allowed to eat the same meal yourself while there if you wish). So not a job that's putting money in your pocket, but you get to help others, burn some time, may interact with others as desired, and may help offset some of your own living expenses as well.
There are a ton of options out there, if you want.
