Spreading caviare, causing greed (7)
I believe the answer is:
avarice
'greed' is the definition.
(avarice is a kind of greed)
'spreading caviare' is the wordplay.
'spreading' is an anagram indicator.
'caviare' with letters rearranged gives 'AVARICE'.
'causing' acts as a link.
(Other definitions for avarice that I've seen before include "Stinginess" , "Extreme greed for wealth" , "Parsimony" , "Rapacity" , "Greed, covetousness" .)
