For this week's (slightly delayed) Wednesday Walkthrough, I'd like to direct you to a friend of mine's incredible post "Why I'm on a Canned Food Strike." Camille says it better than I could've, and she's got great links to back up her stories. Very compelling and discouraging at the same time. I've got some Annie's meals in my cupboard now, and I'm not sure where I'm going to find tomatos, tomato sauce, etc. that's not in a can; but this definitely renews my determination to replace canned food as much as possible.
Remember, baby steps. Don't get overwhelmed and not do anything. Take it one can at a time. Start with a doable goal...replace one canned item per week. You can do it!
