Food delivered by hired cab -- bag extra (3,7)
I believe the answer is:
red cabbage
'food' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'delivered by hired cab bag extra' is the wordplay.
'delivered by' says the answer is hidden in the clue.
'RED CABBAGE' is hidden within 'hired cab bag extra'.
Can you help me to learn more?
(Other definitions for red cabbage that I've seen before include "something to eat" , "pickle ingredient" , "one in a pickle" , "may be handed to you on a plate" .)
