Heat the oil in a large Dutch oven over medium-high heat. Add the shredded carrots, onion, celery and bell peppers; sauté 10 minutes. Add the mushroom, oregano, and garlic; sauté 2 minutes. Add the marinara sauce and wine, and bring to a boil. Reduce the heat, and simmer for about 20 minutes.
Serve over ziti and sprinkle each serving with 2 tablespoons of Parmesan cheese.
Notes
Cheese option: Spoon the sauce over ziti in a baking dish and sprinkle mozzarella cheese on top. Bake until bubbly.
