Preheat your oven to 350. Lightly grease a 9x5 loaf baking pan. Combine all of the ingredients in a large bowl and mix well using your hands. Transfer the mixture to the loaf pan and push down to even it out and ensure there are no air bubbles. Bake for 30 minutes.
While it's baking, making the topping (if you're using it). When the meatloaf comes out of the oven, spread the topping on top evenly. Place back into the oven for 30-35 minutes. Let the meatloaf cool for 15-20 minutes before slicing. Enjoy!
