End of week -- I consumed stuff (7)
I believe the answer is:
satiate
'stuff' is the definition.
('satiate' can be a synonym of 'stuff')
'end of week i consumed' is the wordplay.
'end of week' becomes 'sat' (I've seen this in other clues).
'consumed' becomes 'ate' (eating is a kind of consuming).
'sat'+'i'+'ate'='SATIATE'
(Other definitions for satiate that I've seen before include "Gratify fully" , "Fill to satisfaction" , "stuff" , "content" , "gladden a gourmand" .)
