Dish of a sort, cooked (5)
I believe the answer is:
roast
'dish' is the definition.
(I've seen this before)
'a sort cooked' is the wordplay.
'cooked' indicates an anagram.
'a'+'sort'='asort'
'asort' with letters rearranged gives 'ROAST'.
'of' is the link.
(Other definitions for roast that I've seen before include "Cook (meat) in oven" , "One way to cook meat" , "The Sunday -----, with all the trimmings!" , "Criticise severely" , "Large piece of oven-cooked meat" .)
