Put the bread in a small bowl and over with enough milk to cover. Allow the bread to absorb the milk for 10 minutes. Remove the bread from the milk, and gently squeeze out the milk.
Put the minced beef, the soaked bread, the eggs, the chopped vegetables, and the breadcrumbs . Season generously with salt and pepper and mix everything well.
Divide the mixture into small meatballs no bigger than a walnut.
Add some breadcrumbs to a plate and roll the meatballs so they are evenly coated.
Bake the meatballs in the oven for 20-30 minutes until they are golden brown, turning them half way through.
