In a large bowl, combine the ground pork, ground beef, finely chopped onion, minced garlic, egg, breadcrumbs, chopped parsley, salt, and black pepper. Mix until well combined.

Form Meatballs

Shape the mixture into small meatballs, about 2.5 cm in diameter.

Fry Meatballs

Heat oil in a large frying pan over medium heat. Add the meatballs in batches and fry until golden brown on all sides, about 8-10 minutes. Remove and set aside.

Combine Meatballs and Sauce

Carefully add the fried meatballs to the sauce. Cover and simmer for an additional 10 minutes, allowing the flavors to meld.

Toast Bread

In a separate pan, toast the bread slices over medium heat until golden and crispy, about 2-3 minutes per side.
