Apple sausage in onion gravy is a delicious and comforting dish that combines the sweetness of apples with the savory flavors of sausage and onion. The sausages are cooked until browned and then simmered in a rich onion gravy, which is made from caramelized onions, beef broth, and a touch of apple cider vinegar. The apples add a hint of sweetness and a burst of freshness to the dish. Serve this hearty meal with mashed potatoes or crusty bread for a satisfying dinner.
