Pulse 6 slices of white bread in a food processor to make homemade breadcrumbs. Combine homemade breadcrumbs with meat, egg, milk, salt and pepper in a large bowl.
Cut crusts off remaining 3 slices of bread. Break the pieces up with your hands and combine with meat mixture. The mixture should be very loose.
Using 2 soup spoons, form the meat into balls and fry the balls in oil until brown.
