I also have become inappropriately enamored of canned green beans! I buy the Del Monte "Fresh Cut" green beans in the handy, dandy pull-top 8 oz can! They make a great "no cook, no can opener" snack. I limit myself to 1 can per day because of added salt and wanting to get in some variety.

Good substitute for french fries as a side dish! (but no ketchup of course -- blech)

I buy canned vegetables for when I'm in a hurry but they do sell the NO SALT ADDED for a select canned vegetables (I've found peas, green beans, and corn). GET THOSE! They're still good tasting.

The only canned veggies I buy are tomatoes (no salt added) and artichoke hearts. If I can't buy fresh I always go for the frozen. They tend to have no preservatives and taste more like fresh veggies would.
