There are also a few Japanese, Korean and Taiwanese dishes that use spam. Basically any place that has or has had a US military presence at some point has developed spam based dishes because they leave tons (literally) of the stuff behind when they pull the troops out.

My Hawaiian friend tried the Unmeat brand and said it tasted like the real thing. I enjoyed it a lot, although I've never had "real" Spam.

I have a Chamorro coworker who had a whole rant on how Hawaiian pizza should have spam instead of ham and how awesome spam is. I think it's safe to add the people of Guam to your list.

From Hawaii. This isn't Spam, this is luncheon meat. Or veggie luncheon meat. Sorry to be so snobby about canned meat products, but you can take my Spam from my cold, dead hands. I'll give you all my luncheon meat.
