This amazing list of suggestions on how to stay alive and nourished without spending much money — the gentleman claims to have spent only $10.71 on food for one month — makes for a fascinating read.
2. Stews and soups are miraculous. A big pot with boiling water and whatever you can scavenge dumped in together is the staple of the poor man’s diet. You can dump in whatever you’ve got, along with those free salt and pepper packets, and turn up with something edible and at least remotely nutritious.
3. Keep a hen or two. This seems somewhat silly, but female chickens are very good at producing food. You can unabashedly feed them whatever scraps you have and they produce eggs very regularly. If you’re careful, you can keep them in a small cage in your own apartment; a friend of mine kept one in a pet porter for several months. Just be aware of the smell; you should line their living area with paper and expect to clean it a lot. You can do this by using scavenged newspapers and rotating them daily, but leave the papers that the chicken scratches together for a nest alone.
