Settled down and I consumed stuff (7)
I believe the answer is:
satiate
'stuff' is the definition.
(synonyms)
'settled down and i consumed' is the wordplay.
'settled down' becomes 'sat' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'consumed' becomes 'ate' (eating is a kind of consuming).
'sat'+'i'+'ate'='SATIATE'
(Other definitions for satiate that I've seen before include "Completely satisfy" , "content" , "Fill to satisfaction" , "Overfill - gorge" , "Gratify fully" .)
