Preheat oven to 350 degrees. Line a rimmed baking sheet with two layers of nonstick aluminum foil or use heavy-duty aluminum foil sprayed with cooking spray.
Heat the olive oil over medium-high heat in a nonstick skillet or saute pan. Add the onion, reduce heat to medium and cook for 3-4 minutes or until beginning to soften. Add the green bell pepper and cook another 2-3 minutes.
Add the garlic, dried basil and oregano, stir then take off the heat. Transfer to a large bowl and let cool slightly.
Add the parsley, panko, 1 cup marinara sauce, dry red wine, Worcestershire sauce, Parmesan cheese, Mozzarella, eggs, salt and black pepper. Mix well.
Add the ground beef and pork and mix well again until the meat is thoroughly incorporated, being careful not to overwork it.
Transfer to the prepared double-lined baking sheet and form into a neat loaf shape.
Place in the oven and bake for 55-60 minutes.
Pour the remaining marinara sauce over the meatloaf and bake for another 10 minutes or until an instant-read thermometer registers 165 degrees in the center.
Let the meatloaf rest for 5-10 minutes. Sprinkle with more Parmesan cheese if desired. Slice and serve.
