In a large saucepan over high heat, brown the ground meat in the oil for 3 minutes, breaking it into small pieces with a wooden spoon.
Add the celery, carrot, and garlic and cook, stirring, for 1 minute.
Add the lentils, maple water, and broth. Stir, cover, and bring to the boil.
Reduce heat and simmer 20 minutes or until lentils are tender. Add more maple water or broth if needed.
Add the crushed tomatoes and break the lasagna noodles into pieces directly into the pan. Stir, cover, and simmer over medium heat 15 – 20 minutes, or until the pasta is cooked. If desired, sprinkle with herbs.
