In a large skillet, brown the Ground beef in oil and then drain off access fat (if desired). Add the Onion, Green pepper, Carrot (or celery), Mushrooms, and Garlic and cook for 2 minutes more. Transfer the Ground beef mixture into a large pot and then add all of the remaining ingredients. Stir. Cook on low, partially covered, for about 5 hours, Stirring occasionally. Let the Sauce stand, covered, for about 1/2 an hour and the serve over hot spaghetti. (Freeze leftovers).

*The spices I've placed a star(*) next to are completely optional, add them only if YOU like them. My favorites to add to this sauce are Red pepper, Thyme, Cayenne, Paprika, Sage, and Cinnamon - I usually leave the rest out.

That said if you like your sauce sweet add another 2 tbsp of Sugar, if you like it spicy (i.e not serving it to little kids) add more Chili peppers and red pepper. Experiment!
