Lay the beef slices flat on a cutting board and season lightly with salt and black pepper

In a bowl, combine breadcrumbs, minced garlic, chopped parsley, and basil

Spread a thin, even layer of the breadcrumb mixture over each slice of beef

Roll the beef tightly from one end to form compact rolls

Secure each roll with kitchen twine or toothpicks

Heat olive oil in a large, heavy-bottomed pan over medium heat

Add the beef rolls and sear on all sides until browned

Remove the beef rolls and set aside

In the same pan, add chopped onion and sauté until soft and translucent

Stir in crushed tomatoes, dried oregano, optional sugar, salt, and black pepper

Bring the sauce to a gentle simmer

Return the beef rolls to the pan, spooning sauce over them

Cover and simmer on low heat for 60–90 minutes until the beef is fork-tender

Remove twine or toothpicks before serving
