Haven't had a Spam sandwich since I got out of the Navy. They tasted pretty good back then, though. We had fried spam with fried eggs for breakfast, fried spam sandwiches with a slab of American cheese for lunch, fried spam and potatoes, etc... Spam was considered a basic food group back then. After four years in the Navy I couldn't look at a can of Spam. Might be pretty good on Sprout bread, though.
Cheers,
Gary
