Rinse the green lentils thoroughly under cold running water and set aside.
Chop the yellow onion, carrots, and celery into large, rustic chunks to ensure a hearty texture in the final sauce.
Heat the extra virgin olive oil in a large saucepan over medium heat on the stove top.
Add the onion, carrots, and celery to the pan and sauté for about 8 minutes until the vegetables begin to soften and brown slightly.
Stir in the minced garlic and cook for another 60 seconds until the aroma is released.
Pour in the dry lentils, tomato puree, vegetable broth, dried oregano, sea salt, black pepper, and the bay leaf.
Bring the mixture to a gentle boil, then lower the heat and simmer covered for 25 to 30 minutes until the lentils are tender.
While the sauce thickens, cook the chickpea pasta in a separate pot of boiling salted water according to the package directions until al dente.
Remove the bay leaf from the bolognese sauce and stir in the fresh basil just before serving.
Ladle the chunky lentil bolognese over the cooked pasta and finish with a generous sprinkle of grated parmesan cheese.
