Composer dropping in for something to eat (4)

I believe the answer is:

chop

I'm a little stuck... Click here to teach me more about this clue!

'for something to eat' is the definition.
(chop is a kind of food)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for chop that I've seen before include "Thick slice of meat including rib" , "Abolish, cut of meat" , "Cut of meat; hack" , "Hew" , "Karate punch" .)

I've seen this clue in The Times.
