I'm a little stuck... Click here to teach me more about this clue!

'prepare' is the definition.
(thesaurus)

'print a different diet' is the wordplay.

'to' is the link.

(Other definitions for edit that I've seen before include "Revise for publication" , "Amend and correct" , "Make changes to (text)" , "Change text" , "Prepare text for publication" .)
