Food item setter gets at party? (8)
I believe the answer is:
meatball
'food item' is the definition.
(I've seen this before)
'setter gets at party?' is the wordplay.
'setter' becomes 'me' (the setter of the clue).
'gets' means one lot of letters go next to another.
'party?' becomes 'ball' (ball is a kind of party).
'me'+'at'+'ball'='MEATBALL'
(Other definitions for meatball that I've seen before include "Food made from minced beef" , "Part of dish" , "Small globular piece of mince" , "Lump of seasoned mince" , "Lamb tale? (Anag)" .)
