Heat oven to 350 degrees F.
In a large bowl, stir together olive oil, garlic, onion, carrots, celery, eggs, salt, pepper or worcestershire sauce. Add sausage, beef, eggs, breadcrumbs and parmesan. Mix with a wooden spoon or potato masher until well combined. Form into a loaf, place into a 9x5” nonstick loaf pan.
In a small bowl, mix together marinara and ketchup, spread atop loaves.
Bake for 65-70 minutes, or until an instant-read thermometer registers 160°F in the middle of the meatloaf.
Allow to cool for 15-20 minutes before serving. Or allow to come to room temperature, slice into 1” pieces and store in reusable containers for meatloaf sandwiches, thin-slices as gyros or enjoy on a hamburger bun with all your favorite fixin’s!
