Heat the olive oil in a saucepan and fry the onion and garlic in it for about 2 minutes on a high heat. Stir occasionally.
Add the carrot and potato and sauté for another 2 minutes. Stir occasionally.
Add the spices and bay leaf and stir-fry for another minute.
Add the lentils and deglaze with vegetable stock.
Bring to the boil and simmer on medium heat for about 15 minutes.
Remove the bay leaf and puree the soup.
Add the lemon juice and season with salt and pepper. (You can also try adding half of the lemon juice and see if you like the acidity. In general, the soup should have a good acidity).
