Preheat the oven to 350 degrees. While the oven is heating up, cook the veggies.
In a small skillet, heat olive oil over medium heat and then sauté the chopped onions and peppers until the peppers become soft and onions are translucent. Add the garlic and cook for a couple of minutes or until fragrant. Place the veggies into a large bowl and set them aside to cool.
After the vegetables cool, mix in the ground turkey, sausage, eggs, Worcestershire sauce, spices, bread crumbs, parmesan cheese, 1 cup of shredded cheese, and 1/2 cup of the sauce.
Place the meat mixture on a rimmed baking pan or baking dish coated with cooking spray and form it into a loaf. You can also use a meatloaf pan.
Spread the rest of the sauce over the top of the meatloaf.Bake for 60 - 65 minutes or until the internal temperature reaches 165 degrees.
Take it out of the oven and sprinkle the rest of the cheese over the top. Set the oven to broil.
Broil for a couple of minutes until the cheese melts.
Remove from the oven and let it cool for about 5 minutes before serving.
