In a large pot heat olive oil over medium heat. Add garlic, onion, carrot and celery and cook translucent, about 5 minutes.
Rinse and pick out lentils, then pour into the pot.
Add oregano, rosemary, and bay leaves and salt and pepper to taste. Add water and bring to a boil. Reduce heat to medium-low and continue to cook.
Stir in tomato paste. Cover and simmer until the lentils have softened, 30 to 40 minutes, stirring occasionally. Add additional water if the soup becomes too thick.
To serve, drizzle with 1 teaspoon olive oil and red wine vinegar to taste. Top with freshly grated Parmesan cheese
