Entire repast or just bread (9)
I believe the answer is:
wholemeal
'bread' is the definition.
(I've seen this before)
'entire repast' is the wordplay.
'entire' becomes 'whole' (similar in meaning).
'repast' becomes 'meal' (synonyms).
'whole'+'meal'='WHOLEMEAL'
'or just' is the link.
(Other definitions for wholemeal that I've seen before include "Brown possibly" , "it's so healthy" , "for making bread?" , "Type of flour" , "Like bread" .)
