I'd opt for beans, and here are some reasons why: I'm a wimp, and would never stir up trouble intentionally--couldn't fathom killing one of the animals that had been entrusted to my care. Secondly, I rather like beans, and could definitely get through a week, say, subsisting on them. Third, even though I eat meat, I (somewhat hypocritically) would much prefer to let someone else kill my animals for me. Fourth, I'm not a picky eater, and will generally content myself with what is at hand (very unlike Jack in this regard).
