I have a childhood memory from the 1950's of a kosher canned meat product (kosher Spam). It think it was called Breef. I've been looking for something similar in recent years. There was a product produced in Montreal about 10 years ago, called MK, I believe. Can't find it. There was a product in Israel under the brand name Richard Levy's. It seems to be gone, but there is a brand there now called Poseidon, which I bought in the Machane Yehuda market last month. Has anyone seen something similar in North America?
