Sounds like suitable party food (8)
I believe the answer is:
meatball
'food' is the definition.
(meatball is a kind of food)
'sounds like suitable party' is the wordplay.
'sounds like' indicates a 'sounds like' (homophone) clue.
'suitable' becomes 'meet' ('meet' can be a synonym of 'suitable').
'party' becomes 'ball' (ball is a kind of party).
'meet' is a homophone of 'meat'.
'meat'+'ball'='MEATBALL'
(Other definitions for meatball that I've seen before include "Globular food item" , "Small globular piece of mince" , "portion of food" , "Sphere of cooked mince" , "Such as is found in the Greek dish keftedes" .)
