Heat the oil in your soup pot over medium-low.
Add the sausage. Either cut it into pieces or break it apart as you add it, or as it cooks. You want small chunks. Cook for about five minutes.
Add the garlic and onion and continue to cook for another two minutes.
Add the mushrooms and cook for another two minutes.
Add the herbs, broth, water, marinara, bay leaves, and pepper. Stir. Increase heat to medium-high and bring to a boil, and then reduce to a simmer.
Simmer for about 30 minutes, stirring occasionally.
Break the lasagna noodles into one inch chunks (or however small you want them, bite size) and add to the soup. Cook in the soup for however long the package says, usually about 11 minutes or so.
Ladle soup into bowls and top with 1-2 tablespoons of cheese mixture. Add in any extra mozzarella or basil you want. Enjoy!
