I just posted the 2010 and 2011 MRE menus on the website. You can find the links here:

I wasn't able to find "official" menus on either Natick's or the DSCP's website but the DSCP did have the 2010 and 2011 Assembly Contract Requirements docs for those years and the menus are spelled out inside.
The contents seem to match up with the newly-updated "MRE Improvements" page, too.
