There is Canned Corned beef (mostly originates from Brazil), quality and taste can vary from something thats inedible to something that is acceptable even in a Sandwich with pricing that can vary from £1.50 to £3.00 a can in the UK.
I found I preferred Princes canned corned beef to fresh. I keep a dozen or so 200g tins of it, that get eaten in sandwiches with Branston Pickle. (Larger tins wouldn't get all eaten.)
Then there are canned hams and chicken.
Tinned cured ham is something I've been getting into over the last few months. I've settled on Princes premium brand, which I like in sandwiches with beetroot. Lesser quality isn't nice enough for me.
Cost is important factor when bulk stocking a larder for preparedness,
Buy what you eat and eat what you buy. If you can buy in bulk that should save money, but I wouldn't go for cheaper food because it's "only for survival". The tinned meat I buy has a long enough shelf life that it all gets eaten during normal times.
