Savoury dish, lightly cooked, cut into (7)
I believe the answer is:
rarebit
'savoury dish' is the definition.
(I've seen this before)
'lightly cooked cut into' is the wordplay.
'lightly cooked' becomes 'rare' (I've seen this before).
'cut into' becomes 'bit' (I can't explain this - if you can you should believe this answer much more).
'rare'+'bit'='RAREBIT'
Can you help me to learn more?
(Other definitions for rarebit that I've seen before include "Melted cheese on hot toast" , "Welsh food?" , "Melted cheese with ale on toast" , "Dish of grilled cheese on toast" , "Welsh snack" .)
