The old governor put one in a dish (6)
I believe the answer is:
pilate
'the old governor' is the definition.
'Pilate' can be an answer for 'governor' (Pontius Pilate, Roman governor in Christ's time). I'm not certain of the 'the old' bit.
'one in a dish' is the wordplay.
'one' becomes 'lat' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'a dish' becomes 'pie' (I've seen this before).
'lat' put into 'pie' is 'PILATE'.
'put' is the link.
Can you help me to learn more?
(Other definitions for pilate that I've seen before include "famous old judge" , "Roman governor" , "Magistrate passing death sentence" , "What is truth?, he famously asked" , "Hand-washing Biblical judge" .)
