OUT Canned beans (except in emergencies).
IN Dried beans. More economical, better tasting, space saving and available in far more varieties. Cook a pound once a week and you’ll always have them around (you can freeze small amounts in their cooking liquid, or water, indefinitely). If you’re not sold, try this: soak and cook a pound of white beans. Take some and finish with fresh chopped sage, garlic and good olive oil. Purée another cup or so with a boiled potato and lots of garlic. Mix some with a bit of cooking liquid, and add a can of tomatoes; some chopped celery, carrots and onions; cooked pasta; and cheese and call it pasta fagiole or minestrone. If there are any left, mix them with a can of olive-oil-packed tuna or sardines. And that’s just white beans.
or how about this:
IN Simmer a carrot, a celery stalk and half an onion in a couple of cups of water for 10 minutes and you’re better off; if you have any chicken scraps, even a half-hour of cooking with those same vegetables will give you something 10 times better than any canned stock.

Customize from there, because you may like more vinegar or less, and you undoubtedly will want a little shallot, or balsamic vinegar, or honey, or garlic, or tarragon, or soy sauce. ...
