Stuff and eat as it is cooked (7)
I believe the answer is:
satiate
'stuff' is the definition.
('satiate' can be a synonym of 'stuff')
'eat as it is cooked' is the wordplay.
'is cooked' is an anagram indicator.
'eat'+'as'+'it'='eatasit'
'eatasit' anagrammed gives 'SATIATE'.
'and' acts as a link.
(Other definitions for satiate that I've seen before include "gladden a gourmand" , "Have more than enough" , "Completely satisfy" , "Gratify fully" , "Overfill - gorge" .)
