Cook and crumble ground beef in a large skillet over medium-high heat. Add onion and garlic to beef. Cook until beef is brown and onion is soft. Drain any grease. Season with salt and pepper.
Place the cooked beef in a greased 6-quart slow cooker. Add the broth, both tomatoes, beef bullion, water, tomato paste, parsley, basil, and oregano. Stir well. Cover with lid and cook on low heat for 6 to 8 hours OR on high heat for 3 to 4 hours.
When cooking time is up, stir in the broken lasagna noodles. Cover with the lid and cook another 30 to 40 minutes on low heat, or until noodles are tender. Don't overcook the noodles.
Serve soup warm in individual bowls with desired toppings. Enjoy!
