Filled to satiety (7)
I believe the answer is:
replete
'filled to satiety' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for replete that I've seen before include "Sated by food" , "Well-supplied" , "Stuffed, gorged, sated" , "Full to capacity" , "Chock-a-block" .)
