Chicken sausage is part of the stuffing.
Preheat oven to 375°F. Sauté 2 tablespoons of stock, onion, hot sauce, caraway seeds, parsley and sausage until browned in a cooking-sprayed skillet. Set aside. In covered casserole dish, layer 1/2 the zucchini and 1/2 the squash. Top with the sausage and onion mixture. Next layer the remaining zucchini and squash. Add water or vegetable stock, cover, and cook for 20 minutes. Remove cover, sprinkle with cheese and let cook uncovered for 10 minutes or until brown.
