In a large soup pot over medium-high heat, brown the ground beef, onion, salt, and pepper. Crumble the beef as it cooks. Once the beef is no longer pink, drain the grease.
Blend the can of stewed tomatoes in a blender and incorporate it into the soup pot with the cooked beef.
Add the beef broth, diced tomatoes, mixed vegetables, basil, and parsley. Bring the mixture to a boil.
Once it reaches a boil, stir in the uncooked egg noodles. Cover the pot with a lid, reduce the heat to low, and let the soup cook for 12-15 minutes.
