In a large saucepan or pot over medium-high heat, cook the ground beef and diced onions together until the beef is browned and the onions are softened. Drain any excess grease.
Stir in the beef broth, diced tomatoes, tomato paste, Worcestershire sauce, oregano, basil, and salt and pepper to taste. Bring the mixture to a boil.
Add the uncooked macaroni and frozen mixed vegetables to the pot. Reduce the heat to medium-low, cover, and simmer until the macaroni is tender and cooked through, about 10–12 minutes.
Taste and adjust seasoning with additional salt and pepper, if needed.
Serve hot, garnished with freshly chopped parsley for a touch of freshness and color.
Enjoy!
