Yes, according to Mealtime.org, the public face of the Canned Food Alliance, it is indeed National Canned Food Month. Who knew?
Mealtime.org is a good resource, themed month or no, for those of us still in cupboard cleaning mode. They have a large database of recipes that focuses on canned and preserved ingredients, good for inspiration and help in cleaning out that last can of pineapple, languishing up there since last spring. They also have some canned food FAQs and some nutrition info as well.
I might not quite agree with their tagline, that "Canned Food is the Easy Way to Eat Right" - I think fresh food is often just as easy; but certainly check out the site for recipes and resources.
