When the world as we knew it ended, and the supermarkets were reduced to rubble, it was time to get resourceful.
Check abandoned supermarkets, gas stations, and other places where people once stocked up on emergency supplies. Canned beans, soup, and Spam can sustain you for a while, but don't forget to bring a can opener.
Get familiar with wild greens like dandelion, plantain, and chicory. They're bitter, but they'll keep you going. Just don't eat the pretty flowers – they might be radioactive.
Find a nearby river or ocean, and get fishing! You might catch something decent, or a plastic bottle with a hook in it. Good luck with that.
