In saucepan, heat oil over medium-low heat and add onion, garlic, oregano and hot pepper flakes. Cook, stirring for about 5 minutes or until onion is softened. Stir in lentils and quinoa to coat. Pour in broth and water, tomato and bay leaf and bring to a boil. Reduce heat, cover and simmer gently for about 20 minutes or until lentils and quinoa are tender.
Remove bay leaf and serve sprinkled with parsley. Alternatively, use an immersion blender and puree until smooth and stir in parsley to serve.
