During WWII, we used to eat Spam and pretend it was real meat... We were happy to get it...
Rationing meant ONLY the rich people got enough stamps so they could eat beef or lamb...
Besides our armed forces, we were also feeding the Brits and most especially the Soviets.
SPAM was a big improvement for the latter.
Hawaiians love Spam so I bet they would also preferred a glue steak over the real thing.
