Hospital doctor after a driver to bring food (9)
I believe the answer is:
hamburger
'food' is the definition.
(hamburger is a kind of food)
'hospital doctor after a driver' is the wordplay.
I cannot quite see how this works, but
'hospital' could be 'h' (abbreviation for hospital on maps) and 'h' is found within the answer.
'doctor' could be 'mb' (Bachelor of Medicine, Medicinae Baccalaureus) and 'mb' is found in the answer.
'a' is found in the answer.
The remaining letters 'urger' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to bring' acts as a link.
Can you help me to learn more?
(Other definitions for hamburger that I've seen before include "Staple of the fast food industry" , "beefcake" , "minced beef roll" , "Item of fast food" , "Citizen of Europe" .)
