- 1 (28 ounce) can crushed tomatoes
 - 1 (15 ounce) can tomato sauce
 - 3 (14.5 ounce) cans stewed tomatoes
 - 1 cup red wine
 - 1 cup sliced green olives
 - 4 teaspoons sea salt
 - 2 tablespoons dried basil
 - 2 teaspoons dried oregano
 - 1/2 teaspoon Hungarian paprika
 - 1/2 teaspoon cayenne pepper
 - 3 tablespoons olive oil
 - 1 cup finely chopped sweet onion, divided
 - 1 clove garlic, crushed and chopped
 - 2/3 cup chopped fresh parsley
 - 2/3 cup sliced fresh mushrooms
 - 1 teaspoon brown sugar
 - 3 tablespoons olive oil
 - 3 (4 ounce) links Italian sausage links, casings removed
 - 2 cloves garlic, crushed and chopped
 - 1 teaspoon ground white pepper
 - 1/2 teaspoon ground cumin
 - 1 cup red wine, or more if needed
 
- Mix together the crushed tomatoes, tomato sauce, stewed tomatoes, 1 cup of red wine, green olives, 4 teaspoons of sea salt, basil, oregano, paprika, and cayenne pepper in a slow cooker. Set the cooker to Low.
 - While the cooker is warming up, place 3 tablespoons of olive oil in a skillet over medium heat, and cook 3/4 cup of sweet onion until the onion just begins to soften, about 2 minutes; stir in 1 clove of garlic. Cook the mixture for 3 more minutes before mixing in parsley and mushrooms. Reduce heat, and simmer the mixture for about 10 minutes. Stir in the brown sugar, and mix to dissolve.
 - While the parsley and mushrooms are simmering, heat 3 more tablespoons of olive oil in a skillet over medium heat, and stir in the remaining onion and the sausage. Brown the sausage, breaking the meat up into crumbles as it cooks, about 10 minutes; season the mixture with white pepper and cumin. Pour 1 cup of red into the skillet, and scrape the pan with a wooden spoon to dissolve any brown flavor bits into the wine. Simmer for about 10 minutes; pour the sausage mixture into the skillet with the parsley and mushrooms. Bring to a simmer over medium-low heat just until all the ingredients have had time to introduce themselves to each other, about 10 minutes. Pour the sausage mixture into the slow cooker.
 - Cook on Low for 8 hours to overnight. Add more red wine or water if needed to prevent the sauce from getting too thick and burning on the bottom.
