Bake grouse in a meat dish (5,4)
I believe the answer is:
roast beef
'a meat dish' is the definition.
(type of meal containing meat)
'bake grouse' is the wordplay.
'bake' becomes 'roast' (I've seen this before).
'grouse' becomes 'beef' (synonyms).
'roast'+'beef'='ROAST-BEEF'
'in' acts as a link.
(Other definitions for roast beef that I've seen before include "Typically 7 down dish" , "Joint" , "Traditional English dish" , "Sunday meat?" , "Traditional English food" .)
