Selling aluminum cans for cash is a good place to start. Copper brings more money, but anything made out of copper is closely monitored by scrap yards. Anything made of metal can be sold. Considering the cost of gasoline, you probably should do some walking in order to find things that can be sold. Of course, I do not know where you live, & some areas are less safe to walk in than others. Also, if you have a vehicle, you need to park it some place safe so that you can be (relatively) sure that it will be there when you come back to it. You can also check out homeless shelters, they generally serve some sort of meals to the homeless. I wish you good luck in finding a job fairly quickly. You might check with various apartment complexes about cleaning apartments – frequently they will hire people on a temporary basis & will pay in cash (or at least they used to do this). Of course, up-scale apartment complexes are less likely to hire cleaning people as they mostly have a staff that does the cleaning.
