Preheat oven to 450F.
Grease a 13x9 pan with a thin layer of oil or butter.
Wash and peel vegetables as necessary. Chop all vegetables in a rough chop.
Lay vegetables in the pan. Season with salt and pepper.
Whisk together 2T of olive oil, the broth, and seasonings. Pour over vegetables and toss to coat.
Cover with foil and place pan in the oven. Cook vegetables for 45 min, or until fork-tender.
Meanwhile, brown the meat. Heat a skillet on med-high and brown sausage or chicken on all sides. (You do not need to cook it through.)
Once the vegetables are fork-tender, top with browned meat. Pour balsamic vinegar/wine mixture over the top and return to the oven, uncovered. Continue to bake for another 25-30 min, turning meat halfway through cooking.
To serve: spoon vegetables onto a plate or bowl, top with cooked chicken or sliced sausage. Garnish with fresh herbs.
