Preheat your oven to 350°F (180°C) and grease a 9-inch loaf pan.

In a large mixing bowl, combine the ground beef, ground pork, egg, Parmesan cheese, bread crumbs, garlic, parsley, salt, and pepper. Gradually pour in milk until combined.

Shape the meat mixture into a rectangle about ¼ inch thick on parchment paper.

Sprinkle cheese and chopped greens evenly over the meat rectangle, leaving a border.

Roll the meat mixture tightly from the short end using the parchment paper, then place seam-side down in the loaf pan.

Toss cubed potatoes and sliced carrots in olive oil and season, then distribute around the meatloaf in the pan.

Bake for 45-60 minutes until the internal temperature reaches 160°F (70°C).

Let the meatloaf rest for 5-10 minutes before slicing and serving with roasted potatoes and carrots.
