Chicken Soup:
Boil whole fryer chicken for 1 and a half hours. Amount of water should be enough to submerge the chicken, and you'll have to add more at least once during the boiling.
While boiling, cut up some celery, an onion, and some carrots.
Once the chicken tears away from the meat when you jab it with a fork and twist, remove the chicken from the water. Add veggies, a cup or two of rice, and begin removing the meat. Easiest way to do this that I've found is to remove it with your hands, though be careful as the meat cools unevenly so you'll probably burn your hands once or twice. Throw bones away, put meat back in broth. Boil for another 30 minutes or until the veggies are done. Add 1-2 Tbs of salt.
This will provide dinner and keep me and a roommate fed for at least a week. Total cost ends up being around 15 bucks, though that'll probably be more for everyone else since New Mexico's cost of living is cheap. Adding a lot of veggies or a lot of rice will make it less soupy.
