Caviare might produce such greed (7)
I believe the answer is:
avarice
'greed' is the definition.
(synonyms)
'caviare might produce' is the wordplay.
'might produce' is an anagram indicator (I've seen this in other clues).
'caviare' anagrammed gives 'AVARICE'.
'such' acts as a link.
(Other definitions for avarice that I've seen before include "Stinginess" , "One of seven deadly sins" , "Greed - caviare (anag)" , "excessive desire for wealth" , "Wanting to be rich" .)
