Add the garlic, spices, dried thyme, carrots, celery and peppers and cook for 5 minutes.
Add the tomatoes, stock, courgettes and fresh thyme and cook for 20 - 25 minutes.
Take out the thyme sprigs. Stir in the lentils and bring back to a simmer. Serve with wild and white basmati rice, mash or quinoa.
