Greed putting odd bits of veal into a staple foodstuff (7)
I believe the answer is:
avarice
'greed' is the definition.
(avarice is a kind of greed)
'odd bits of veal into a staple foodstuff' is the wordplay.
'odd bits of' indicates alternate letters.
'into' is an insertion indicator.
'staple foodstuff' becomes 'rice' (rice is a staple food).
The alternating letters of 'veal' are 'va'.
'a'+'rice'='arice'
'va' put inside 'arice' is 'AVARICE'.
'putting' is the link.
(Other definitions for avarice that I've seen before include "Parsimony" , "Wanting to be rich" , "Greed, covetousness" , "Insatiable lust" , "Greed - caviare (anag)" .)
