1. In a large skillet with tall sides, add onions, garlic, and ground beef; cook for 6-8 minutes, or until beef is cooked through; use a wooden spatula to break apart while cooking. Drain off fat.
2. Add tomato paste, broth, water, oregano, basil, black pepper; whisk well to combine ingredients; bring to a boil.
3. Add spaghetti, lightly pressing down so sauce comes over it. Lightly stir it every few seconds, so that spaghetti combines with sauce/meat. Simmer for 17-20 minutes or until spaghetti is cooked through and sauce has thickened.
4. Serve immediately topped with fresh parmesan cheese.
