The fatty tuna I ate last night looked like Spam

Except imagine twice the fat, such that the tuna meat separated into what looked like mini slices of Spam. If I closed my eyes and asked my dinner companion to distract me with inane rambling, I could stomach it. It just tasted like tuna, but fattier. However, with my eyes open, it was one of the least appetizing $5 pieces of fish I've ever seen, much less eaten.
