I'd hissed -- terrible bit of food on the table! (4,4)
I believe the answer is:
side dish
'bit of food on the table' is the definition.
'i'd hissed terrible' is the wordplay.
'terrible' indicates anagramming the letters.
'id'+'hissed'='idhissed'
'idhissed' with letters rearranged gives 'SIDE-DISH'.
(Other definitions for side dish that I've seen before include "something extra, of course" , "Accompaniment at mealtime" , "It goes with a main course" , "supplementary course material" , "Food item subordinate to the main one" .)
