Boil the macaroni in salted water for about 8 minutes until tender; then, drain and set aside.

Cook the ground beef, onion, green pepper, garlic, salt, and pepper together in a large skillet over medium-high heat until the beef is browned.

Simmer by adding the tomato sauce, ketchup, beef broth, Worcestershire sauce, apple cider vinegar, mustard powder, and paprika.

Combine the drained macaroni with the sauce mixture, stirring until it's all evenly coated.

Serve hot, garnished with a generous sprinkle of shredded Cheddar cheese and fresh parsley.
