- Fill a large pot with water, salt the water and bring to a boil. Cook the pasta according to package directions. *You can either finish cooking the pasta and leave it in a colander and use the same pot for the sauce or you can start making the rest of the recipe in a separate pot while the pasta is cooking.  
- In a separate pot or the one from the pasta (see note above), add the butter and onion to the pot and saute, stirring frequently, until the onions are translucent, about 4 minutes.  
- Add the garlic to the onions and cook for 1 minute, stirring frequently. 
 
 
- Add ground beef and cook until browned, you can cook this in a separate pan if you'd like less fat and add it to the onions after cooking. 
- Add green pepper and cook until soft, about 5 minutes.  
- Add the diced tomatoes, sauce, juice, paste, sugar, spices, and Worcestershire Sauce. Cook until evenly heated. 
- Stir in the cooked pasta and stir to coat and add salt and pepper to taste.
