I don't can meat, but I count 6 tins of Spanish sardines in my food supply that I draw on through the year, and I just refresh it when the local Spanish specialty store has a sale on. Fresh or at least canned sardines are the bomb when sautéed in oil and served over olives and cucumbers, or with cooked eggplant. And Spam - love it. Can't get enough of it. Love it in my loco moco. Got a case of Span that will last a fair long time in the larder. I know that Spam is pretty salty but I can get past that, I find the canned corned beef to be too salty for my tastes. Hey, if we're going to be reduced to rations during a disaster, there's no reason not to eat well.
Wait and you might find Spam offered with air tight plastic lids to put on after opening, it means you don't have to eat a whole can all at once, but you can save it for a while until the loco moco calls again. I've used the same 2-3 plastic lids for years.
I can't seem to put Costco canned chicken into the family's food rotation, I donated 3-4 cans to the food bank earlier this year.
