In a dutch oven or large skillet, brown ground chuck and Italian sausage over medium to medium-high heat. Remove meat and drain excess fat.
Heat oil in skillet. Add onion, bell pepper, mushrooms and few pinches of salt and pepper. Sauté for 5 minutes, or until veggies are tender. Add garlic and sauté for additional 2 minutes. Stir in tomato paste and red wine. Stir until fully combined.
Return meat to the skillet or dutch oven and stir until everything is mixed. Add crushed tomatoes, diced tomatoes, tomato sauce, salt, Italian seasoning, sugar, crushed red pepper, fresh parsley and bay leaf. Stir together and bring to a simmer. Cover and reduce heat to medium-low and simmer for 1 hour.
Remove cover and stir in basil and parmesan cheese. Taste and adjust seasonings if needed. Cover and simmer for additional 1 and 1/2 hour, or longer. The longer this sauce cooks, the better it will be. When sauce is almost ready, go ahead and cook pasta according to package instructions.
Serve with cooked spaghetti, or other pasta of choice.
