Baker baked quick meal (9)
I believe the answer is:
breakfast
'meal' is the definition.
(I know that breakfast is a type of meal)
'baker baked quick' is the wordplay.
'baked' indicates anagramming the letters.
'quick' becomes 'fast' (similar in meaning).
'baker' is an anagram of 'break'.
'break'+'fast'='BREAKFAST'
(Other definitions for breakfast that I've seen before include "First meal of the day" , "See 5" , "First meal at Tiffany's" , "croissants?" , "Morning meal" .)
