Meted out while she decorated the exterior (6,2)
I believe the answer is:
dished up
'meted out while' is the definition.
I can't judge whether this definition defines the answer.
'she decorated the exterior' is the wordplay.
'decorated' becomes 'did up' (I've seen this in another clue).
'the exterior' means one lot of letters goes inside another (some letters go on the outside of others).
'she' going into 'didup' is 'DISHED UP'.
Can you help me to learn more?
(Another definition for dished up that I've seen is " served meal".)
