Meant to have eaten outside — is in France stuck inside (8)
I believe the answer is:
destined
'meant' is the definition.
(thesaurus)
'is in france stuck inside' is the wordplay.
'is in france' becomes 'est' ('is' in French).
'stuck' becomes 'dined' (I can't justify this - if you can you should believe this answer much more).
'inside' is an insertion indicator.
'est' put within 'dined' is 'DESTINED'.
'to have eaten outside' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
(Other definitions for destined that I've seen before include "Designated" , "Fated, fore-ordained" , "Intended; doomed" , "Didn't see, being fated" , "Intended (for a particular end)" .)
