Go along for something to eat (4)
I believe the answer is:
roll
I believe this clue is a double definition.
'go along' is the first definition.
(thesaurus)
'something to eat' is the second definition.
(roll is a kind of food)
'for' is the link.
(Other definitions for roll that I've seen before include "Move like a ball" , "Swell" , "start recording film" , "Sound of a drum or a list of names" , "Drums sound" .)
