Heat olive oil in a large Dutch oven on medium high heat and add beef and sausage, breaking up the chunks. Brown meat all over.
Lower heat to medium. Add celery, carrots, onion, garlic, oregano, basil, thyme, parsley, salt and pepper. Cook until vegetables are tender, but do not caramelize. Add tomato paste and red wine and cook for about 2-4 minutes, until slightly reduced.
Add whole tomatoes and break up with a wooden spoon to desired thickness & texture. Add vinegar and stevia & blend well. Reduce heat to a simmer, cover and cook for 1 1/2 to 2 hours. Be sure to taste the sauce every half hour to ensure you get the flavor you want.
Serve with your favorite pasta noodles and top with grated Parmesan cheese.
