Seafood dish of the month followed by canned soup (7)
I believe the answer is:
octopus
'seafood dish' is the definition.
'the month followed by canned soup' is the wordplay.
'the month' becomes 'oct' (Oct is an example**).
'followed by' means one lot of letters go next to another.
'canned' indicates an anagram (canned can mean drunk).
'soup' is an anagram of 'opus'.
'oct'+'opus'='OCTOPUS'
'of' acts as a link.
(Other definitions for octopus that I've seen before include "Sea-creature" , "Scoot up (anag.)" , "Spineless creature" , "army swimmer" , "Eight-limbed cephalopod" .)
