Slow cooker lasagna soup from A Farm Girl Dabbles is an alternative way to enjoy this classic family meal. Chicken breast is combined with dried herbs, spices, mushrooms and tomato sauce in the slow cooker and simmered for hours. During that time, the flavors meld and the soup becomes rich and delicious. Prior to serving, fusili pasta is cooked separately and added to the soup. Each bowl of soup is topped with cubes of mozzarella that melt and add just the right amount of cheesy flavor.
