Soak the fresh breadcrumbs in milk for about 5 minutes until moist and fluffy.

In a mixing bowl, combine soaked breadcrumbs with egg yolks, grated cheese, minced garlic, salt, and black pepper to form a thick paste.

In a large bowl, mix ground beef and ground pork gently, then add breadcrumb mixture and chopped parsley, blending well.

Using a ¼-cup measuring cup, scoop out portions and roll into balls, placing them on a plate.

In a skillet, heat olive oil over medium-high heat and brown meatballs for about 6-7 minutes until golden and reaching 165°F internal temperature.

Optionally, transfer browned meatballs to tomato sauce and simmer for 10-15 minutes.

To bake, preheat oven to 425°F and bake meatballs for 20-25 minutes until browned and cooked through.
