I follow dad's vehicle to get something to eat (8)
I believe the answer is:
pastrami
'something to eat' is the definition.
(pastrami is a kind of food)
'i follow dad's vehicle' is the wordplay.
'follow' means one lot of letters go next to another.
'dad's' becomes 'pa's' (pa can mean someone's father).
'vehicle' becomes 'tram' (tram is a kind of vehicle).
'pas'+'tram'='pastram'
'i' put after 'pastram' is 'PASTRAMI'.
'to get' acts as a link.
(Other definitions for pastrami that I've seen before include "smoked joint" , "Meat dish" , "Spiced sliced beef" , "Seasoned smoked beef, served in thin slices" , "Highly seasoned cut of smoked beef" .)
