Small wood — and small pieces of meat (6)
I believe the answer is:
steaks
'pieces of meat' is the definition.
(a steak is a piece of meat)
'small wood and small' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'wood' becomes 'teak' (type of timber).
'and' says to put letters next to each other.
'small' becomes 's' (abbreviation - e.g. clothes size).
's'+'teak'+'s'='STEAKS'
(Other definitions for steaks that I've seen before include "Cuts of meat" , "They can be round, T-bone or fillet" .)
