Sausage Casserole Supreme is a hearty and flavorful dish that combines sausages, vegetables, and a rich tomato sauce. The sausages are browned to perfection and then simmered with onions, bell peppers, and garlic. The tomato sauce is made with a blend of diced tomatoes, tomato paste, and a variety of herbs and spices. The casserole is then baked in the oven until the sausages are cooked through and the flavors have melded together. This comforting casserole is perfect for a cozy family dinner or a potluck gathering.
