If you are near the ocean or a river then learn how to fish, build a crab pot and pick rock oysters. Freshwater crays from inland dams make a great meal. a couple of cherry tomato plants in pots. i found when living up north that there were always bananas and paw paw ect growing somewhere near roads ect. working at woolies you should check out back for the spoils they toss. The hungrier you get the more wise you get.
