Obviously the correct answer here is pork, because then you can set your machine to "Infinite Bacon" and build yourself a Bacon Bridge to escape the island.




That being said, I voted for chicken. Beef has more direct variety, but chicken is mild enough that I think you can end up getting even more variety out of it based on the zillions of ways to prepare it.

I thought about running fish, but couldn't think of something I'd want to eat forever besides cod. I've already eaten enough salmon to hold me over for the rest of my life.
