Small fried meatball (7)
I believe the answer is:
rissole
(Other definitions for rissole that I've seen before include "Fried meat/breadcrumb ball" , "Fried and breadcrumbed dish" , "Minced meat or fish deep fried in egg and breadcrumbs" , "Fried ball of minced food" , "Meatball fried in crumbs" .)
