Two chaps can share such meat (5)
I believe the answer is:
halal
'meat' is the definition.
(halal meat, meat conforming to Muslim law)
'two chaps' is the wordplay.
'two chaps' means two substitutions for 'chap'.
'chap' becomes 'hal' ().
'chap' becomes 'Al' (man's name).
'hal'+'al'='HALAL'
'can share such' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for halal that I've seen before include "Conforming to Muslim dietary laws" , "specially prepared type of meat" , "(Meat) from animals slaughtered according to Muslim law" , "Meat slaughtered in accordance with Islamic law" , "Meat, clean to Muslims" .)
