In a large pot, heat the oil over medium heat. Add the ground beef to the pot and cook until browned, breaking it apart with a spoon as it cooks. Season with salt and pepper to taste.
Then, add the chopped onion and crushed garlic, and sauté until softened and fragrant, about 5 minutes.
Once the beef is browned, pour in the unsweetened tomato juice and beef broth. Stir well to combine.
Add the bay leaf to the pot for added flavor. Allow the mixture to come to a simmer, then reduce the heat to low and let it simmer for 10 minutes to allow the flavors to meld together.
Meanwhile, break the lasagna noodles into small pieces. You can do this by hand or place them in a resealable plastic bag and crush them with a rolling pin.
Add the broken lasagna noodles to the pot, stirring to ensure they are fully submerged in the soup.
Continue to simmer the soup for an additional 10-15 minutes, or until the noodles are cooked through and tender.
While the soup is simmering, prepare the topping. In a small bowl, combine the crumbled feta cheese, crumbled cottage cheese, and chopped fresh parsley.
Once the noodles are cooked, taste the soup and adjust the seasoning as needed with salt and pepper.
To serve, ladle the Lasagna Soup into bowls and top each serving with a spoonful of the cheese and parsley topping.
Garnish with additional fresh parsley if desired, and serve hot.
