I avoid canned beef and chicken where possible.
It's laden with fat, nitrates, and preservatives. I remember
trying to cook canned beef once - I had to slice off the top layer
of fat, and even then, when I cooked it, I didn't even have to add
oil and salt.
Only canned tuna works for me. It's cheap, relatively healthy,
and a great source of protein.
But Corned Beef is so nice though I eat it liek 1 can a year

Oh man if you stir fry Belgian Endives with corned beef it's
like to die for
