Happen to store cooked dish for resident (8)
I believe the answer is:
occupier
'resident' is the definition.
(synonyms)
'happen to store cooked dish' is the wordplay.
'happen' becomes 'occur' (synonyms).
'to store' means one lot of letters goes inside another.
'cooked dish' becomes 'pie'.
'occur' going around 'pie' is 'OCCUPIER'.
'for' acts as a link.
(Other definitions for occupier that I've seen before include "One in residence" , "One living in house" , "Squatter" , "Person in position" , "One in possession of property" .)
