This vegetarian Bolognese uses lentils, vegetables, tomato and herbs for a thick sauce to spoon over pasta. The source provides no ingredient list, so this version supplies a measured, clearly identified meat-free formula rather than implying it was present in the original. Simmer until the lentils are tender and the sauce clings to a spoon. Add a splash of pasta water if it becomes too thick before serving. Heat oil in a saucepan over medium heat. Add onion, carrot and celery and cook 7 minutes until softened. Stir in garlic for 30 seconds. Add lentils, tomatoes, broth, tomato paste, oregano and salt. Bring to a boil, then partially cover and simmer 30 to 40 minutes, stirring occasionally, until lentils are tender. Add a little water if needed.
