Melt oil in a large saucepan over medium heat. Add carrots, onions and cook for 10 minutes, stirring occasionally. Add celery, garlic and chilli and cook for a further 5 minutes. Add chopped tomatoes, stock (or water), bay leaves, oregano and lentils and bring to the boil. Reduce heat and simmer, stirring occasionally, for 30 minutes. Season with salt and pepper, and stir through parsley.
