is VERY unlikely to have contained a Flour Mill and an Oven... so I can see fruit in season, nuts in season, meat, eggs, salady greens and maybe the occasional raw root provided by Mr. BigBang. Not wheat, rice, soy, dairy, etc. unless in very small quantities ... and those small quantities after the accidental discovery of fire and 2-rocks-make-a-grinder discovery because the stuff, any of it, doesn't naturally grow in large fields.

To each his or her own opinion then ... eh?
