Preheat your oven to 350°F (175°C).

In a medium skillet over medium heat, drizzle olive oil and sauté chopped red onion, diced red bell pepper, and minced garlic for about 5-7 minutes until softened.

In a large mixing bowl, combine the sautéed vegetables with ground beef, Italian-style breadcrumbs, grated Parmesan cheese, eggs, tomato paste, salt, and black pepper. Mix thoroughly.

On parchment paper, shape the meat mixture into an 8"x15" rectangle.

Layer deli ham, fresh basil, and mozzarella cheese along the center of the meat rectangle.

Roll the meatloaf tightly away from you, sealing the edges well, and place seam-side down on a baking sheet.

Bake for about 1 hour, or until the internal temperature reaches 160°F (70°C). Tent with foil halfway through if needed.

Let the meatloaf rest for about 10 minutes before slicing and serve over pasta or zucchini noodles with marinara sauce.
