The aroma of rosemary will fill your kitchen and get them running for a tasty soup to share. Serve up some crusty bread alongside to a heart-warming meal.
In a soup pot, heat oil over medium heat and cook onion, garlic, celery, rosemary and hot pepper flakes for 5 minutes or until softened. Stir in lentils and pour in broth. Bring to a simmer. Cover and cook for 20 minutes. Stir in tomatoes, cover and cook for about 10 minutes or until lentils are tender.
