In just about 45 minutes you can make this hearty casserole, hot and bubbling from the oven and featuring a flavorful combination of sausage, ground beef, spinach and white beans in a delectable mushroom sauce.
Cook the sausage, beef and onion in a 12-inch oven-safe skillet until the sausage and beef are well browned, stirring often to break up beef. Pour off any fat. Stir in the spinach and cook until the spinach is wilted.
Stir the soup, liquids and beans in the skillet.
Bake for 30 minutes or until the sausage mixture is hot and bubbling.
