Lebanese Lentil Soup

Wash the lentils in a strainer until the water runs clean, drain and set aside.
In a large pot heat the oil and sauté the onion until softened.
Add the carrot and potatoes. Continue to cook for another 1-2 minutes, stirring continuously.
Add all remaining ingredients, except the lemon.
Stir and bring to a boil, reduce heat and simmer for 40 minutes.
Remove from heat and allow to cool slightly before blending to avoid burning yourself.
Using an immersion blender or high speed blender, blend until smooth and creamy.
Adjust seasoning to taste. Serve with a squeeze of lemon juice.
