Using a large saucepan or pot, heat the olive oil over meduim-high heat, add the onion and garlic and sauté for about 3-4 minutes, until onion becomes translucent.
Add ground beef and Italian sausage and cook about 4 minutes more, breaking it up as you go, until it’s mostly browned.
Add mushrooms and cook 3-4 minutes more.
Add the tomato sauce and tomato paste mixture, mix well. Add the Worcestershire sauce and wine, stir, and bring to a boil.
Reduce heat to low, add the herbs and seasonings, mix well, and simmer for at least 1 1/2 hours or more, adding olives after sauce has cooked for 30 minutes if using.
