4 kg ground beef (or half lamb)
4 large onions, grated
6 garlic cloves, minced
1 cup milk
6 slices bread (or 3 cups breadcrumbs), soaked in milk
6 eggs
1 cup fresh parsley, finely chopped
1/4 cup dried mint (or 1 cup fresh, finely chopped)
3 tbsp dried oregano
2 tbsp salt
1 tbsp pepper
Olive oil for baking or frying
Soak the bread in milk, then squeeze out excess and crumble into a mixing bowl.
Combine all ingredients in a huge bowl. Mix well but avoid over-mixing (which toughens meatballs).
Form meatballs: About walnut-sized (~30g each). You should get ~160–180 meatballs.
Cook:
Bake: Preheat oven to 200°C (390°F), place meatballs on greased/lined trays, brush with olive oil, and bake ~20–25 mins, turning once.
Pan-fry: Heat oil in large pan, fry meatballs in batches until browned and cooked through.
Serve hot with tzatziki.
