Pre heat the oven to 375 degrees.
In a sauté pan, heat oil over medium heat and add the onions. Cook the onions until they are just starting to soften and then add the garlic and cook for one minute longer. Remove from heat.
In a large bowl and using your hands, mix the meat, breadcrumbs, egg, cheese, onion and garlic, salt, pepper, parsley and half the can of tomato sauce.
Grease a baking dish and form the meat into a "loaf" or whatever shape you choose. Bake until the meat is browned on top; about 30 minutes. Pour the second half of the tomato sauce over the meat and bake for another 30 minutes.
Meanwhile, bring a large pot of salted water to a boil. Cook the noodles according to the package directions. Drain and toss with a bit of olive oil.
Remove the meatloaf from the oven and skim off the fat from the sauce that's accumulated in the baking dish. Add the noodles to the dish and toss with the sauce. Garnish with parsley and serve with more cheese.
