Slice of meat, twice as quick (4-4)
I believe the answer is:
chop-chop
'quick' is the definition.
(I've seen this before)
'slice of meat twice' is the wordplay.
'slice of meat' becomes 'chop' (I can't explain this - if you can you should give a lot more credence to this answer).
'twice' says to double the letters.
'chop' duplicated is 'CHOP-CHOP'.
'as' is the link.
Can you help me to learn more?
(Other definitions for chop-chop that I've seen before include "Quickly!" , "Hurry up!" , "Get a move on!" .)
