Meat soup & Fish cakes
Someone said hot food's better & more efficient, but that's not true.  

Example:
Slave A eats 3 meat/day;   Slave B eats 3 vegies /day; 
   [note that "meal soup" says it's meat & water, but actually it's "meat & vegie soup" since includes vegetables!]

SO:   to feed both:   We'd need 6 soups per day   [which requires 6 meat + 6 vegies + lost production time spent cooking!]   
*OR*  just 3 meat & 3 vegies.  (HALF as much)

So actually  hot foods cost *MORE* (2x as much!)  & are *LESS* efficient, not more.
Correct?    (tutorial is useless & there's no good glossary or anything to look things up)

[Would like to start a Glossary on Wiki but lots don't understand myself]
