Steve B, yes I have used canned ham. Yes, it tastes like ham. I store some of the cans from Aldi's. I do not know what brand they are.
I have taken them from the can and baked in the toaster oven with a brown sugar, mustard topping. If you really want to kick it up a notch, put some pineapple on top.
If you try to slice and fry it for a sandwich, it has a tendacy to fall apart, but who will know, once it is between bread. It also works out as a seasoning meat for beans. Goes great in casseroles, and egg dishes.
Good camping food, if you keep in mind, it is not a spiral sliced ham. It is like chunks of ham molded together. That is why it falls apart when sliced, out of the can, to fry. It doesn't fall apart as much when baked, then sliced.
It has been many years since I have tried other more expensive brands. Might work out better. There are some more expensive brands, I have read good reviews about, but cost way more than I care to spend for my uses.
Hope this helps. Terry R.
