SPAM - some parts are meat.
(Just in case you weren’t savvy.)

In HI and CA, you will find Spam Musubi (Spam sushi!) in the local stores or in CA, at the Japanese grocery stores! Best eaten cold.

I don’t know that I’d advise buying a can of this stuff at your local grocery, opening it up on a piece of bread, and calling it a meal. But when I was in Hawaii, the McDonald’s had fried Spam as one of the breakfast meals. It was served with rice and scrambled eggs. Maybe it was the McD’s grill grease mixed with it, or maybe it was all presentation, but it wasn’t that bad.

A month later, I bought some at the store, sliced it, and fried it, and it was pretty horrible. So maybe I didn’t cook it right, or maybe it’s bad unless it’s at a McDonald’s. Not sure.
