In a large pot (you need to be able to add all the zucchini to it), add the oil, onion, garlic, ground meat, and sausage. Cook over medium high heat, breaking up the chicken until cooked through.
Stir in the wine, balsamic vinegar, tomato paste, Italian seasoning, and sugar. Cook for 2 more minutes.
Stir in the crushed tomatoes and marinara sauce.
Reduce heat and cook for 10 to 15 minutes, stirring occasionally.
