Put 1/4 cup of the water in a large pot and add the carrots, celery, parsnips, rutabaga, turnip and zucchini. Steam until tender, about 10 minutes. Add the broccoli, cauliflower, stock, remaining 1/2 cup of water, and 2 tablespoons of the butter. Bring to a boil and reduce to medium heat. Cook about 15 to 20 minutes. Add the pasta and the remaining 1 tablespoon of butter. Heat thoroughly and serve with grated Parmesan cheese.
In a large bowl, combine all vegetables. In a small separate bowl, combine garlic, oil, herbs, balsamic vinegar and brown sugar. Mix marinade with vegetables, cover with plastic wrap and let sit up to 2 hours. Arrange vegetables on a baking sheet, sprinkle with salt and pepper. Roast in a preheated 500 degree F oven for 35 to 40 minutes or until cooked through.
