Observed it's hardly refrigerated (7)
I believe the answer is:
noticed
'observed' is the definition.
(noticing is a kind of observing)
'hardly refrigerated' is the wordplay.
'hardly' becomes 'not' (I've seen this in another clue).
'refrigerated' becomes 'iced' (I've seen this in another clue).
'not'+'iced'='NOTICED'
'it's' acts as a link.
(Other definitions for noticed that I've seen before include "Spotted" , "remarked" , "Became aware of" , "Observed or saw" , "regarded" .)
