How to Make It
- Heat 1 tablespoon oil in 12-inch skillet over medium-high heat until just smoking. Brown sausage well, breaking up large pieces with wooden spoon, about 5 minutes; transfer to slow cooker.
- Pour off all but 2 tablespoons fat from skillet, add onions, and cook over medium heat until softened and lightly browned, 8 to 10 minutes. Stir in garlic, tomato paste, oregano, and pepper flakes and cook until fragrant, about 1 minute. Stir in wine, scraping up any browned bits, and simmer until thickened, about 5 minutes; transfer to slow cooker.
- Stir in crushed tomatoes, diced tomatoes, and tomato sauce. Cover and cook until sauce is deeply flavored, 9 to 10 hours on low or 6 to 7 hours on high.
- Microwave bell peppers with remaining 1 tablespoon oil in bowl, stirring occasionally, until tender, about 5 minutes. Using large spoon, skim excess fat from surface of sauce. Stir in bell peppers and parsley and season with salt and pepper to taste. Serve.
