Preheat oven to 375 degrees. Spread your chicken parts out into a roasting pan. Cut up sausage into 2 inch pieces and scatter in roasting pan. Add the quartered potatoes. Scatter the garlic over everything.
Pour the bottle of salad dressing over the ingredients in the pan evenly. Top with the grated parmesan cheese.
Bake uncovered in the pan for approximately 1 to 1 and 1/2 hours until nicely browned. Stir occasionally to prevent ingredients from sticking to the pan. MANGIA BENE.
