One pal cheesed off said nothing (4,4,5)

I believe the answer is:

held ones peace

'said nothing' is the definition.
(to hold one's peace is to refrain from comment)

'one pal cheesed off' is the wordplay.
'off' indicates an anagram.
'one'+'pal'+'cheesed'='onepalcheesed'
'onepalcheesed' is an anagram of 'HELD ONES PEACE'.
