Reconcile this writer with a large, satisfying feast (6,4)
I believe the answer is:
square meal
'satisfying feast' is the definition.
(a filling meal)
'reconcile this writer with a large' is the wordplay.
'reconcile' becomes 'square' (square can mean to reconcile or resolve).
'this writer' becomes 'me' (the person who wrote the clues).
'with' is a charade indicator (letters next to each other).
'large' becomes 'L' (eg in clothes sizes).
'square'+'me'+'a'+'l'='SQUARE MEAL'
(Other definitions for square meal that I've seen before include "Satisfying food" , "proper food" , "Substantial repast" , "Courses" , "apparently not a round of sandwiches?" .)
