'those inside' is the definition.
I can't judge whether this definition defines the answer.

'happens to include pastry dish' is the wordplay.
'happens' becomes 'occurs' ('occur' can be a synonym of 'happen').
'to include' indicates putting letters inside.
'pastry dish' becomes 'pie' (I've seen this before).
'occurs' enclosing 'pie' is 'OCCUPIERS'.

'for' is the link.
