[is it kosher?]

Once upon a time, Loof was available. And before that, Breef:

[On Nov. 14, the Israeli media outlet Ynetnews sounded the death knell for a staple of the country’s military diet: Loof, Israel’s kosher alternative to Spam.

Thanks to a policy of mandatory conscription, the Jewish state, in effect, had been force-feeding Loof — a colloquially corrupt short form of “meatloaf” — to its citizens since the nation’s founding. The resulting trauma alluded to in Gil Marks’ “Encyclopedia of Jewish Food” is understandable: “Many Israeli soldiers insist that Loof uses all the parts of the cow that the hot dog manufacturers will not accept, but no one outside of the manufacturer and the kosher supervisors actually know what is inside.”

Loof anecdotes are ubiquitous and diverse: There’s the one about a current 20-year-old Israeli soldier who was handed a can of meat dated 1988. “It wasn’t bad,” the soldier said. “It just felt weird eating something that was older than me.”]
