My first thought after the 'pig' word was placed in the article title was to google 'spam jerky recipes' cooked with a solar cooker so as to attempt to be carbon neutral, but then I thought, wait a second, the spam still has to get into the can, and if so I would prefer recyclable poptop spam cans. So I guess that's out too.
