Next, in a large bowl put the minced meat with the bread crumbs, the mustard, the yolks from the two eggs, half the Parmesan cheese, the oregano and the mixture of rosemary and garlic that you made in the mortar. Mix everything together well until the ingredients are blended and then set aside for a couple of minutes. Next, separate the mixture into portions and form the meatballs with your hands. Set aside.
