Wash and clean the spring onions and cut them into rings. Rub off the thyme.
Heat olive oil in a pot and sauté the onion. Stir in the tomato paste and curry and sauté briefly. Rinse the lentils in a colander in cold water and add to the onions and sauté for 1-2 minutes.
Deglaze with a dash of lime juice. Pour in water and add the soup seasoning and thyme. Simmer for a few minutes.
Using a strainer, remove some of the lentils from the soup and keep warm for chowder.
Simmer the remaining soup a bit more and then puree with a hand blender.
Season to taste with salt and freshly ground pepper. Divide the lentils into warmed bowls and pour the soup over them.
Garnish with fresh thyme and serve hot!
