Bring a pot of water to a boil and prepare macaroni as directed on the label. (Watch your timer, do not overcook, usually 7 minutes, and drain.)
Heat a large frypan on medium, add olive oil and ground beef, breaking it up into smaller pieces as it cooks, 2-3 minutes (some pieces should still be pink.) drain off the grease.
Add chopped onions, green pepper, and garlic to the meat, stirring every few minutes. Cook for 5-6 minutes, or until vegetables are tender.
Add oregano, basil, parsley, salt, and Worcestershire sauce. Saute for 2-3 minutes.
Add tomatoes with juice. Reduce heat, cover, and simmer for 10 minutes.
Add cooked and drained pasta and gently toss.
Cover and simmer for 2-3 more minutes.
Ladle into warm bowls, and enjoy.
