Step 1

Heat the oil in a small soup pot. Add the onion and sauté over medium heat for 5 minutes, or until translucent.

Step 2

Add the garlic, celery, and carrots and sauté for 3 to 4 minutes longer.

Step 3

Add the water along with the remaining ingredients except the salt and pepper. Bring to a slow boil, then lower the heat, cover, and simmer until the lentils and vegetables are done, about 30 to 40 minutes.

Step 4

Stir in the parsley, then add a bit more water if the soup is too dense, but let it stay nice and thick. Season with salt and pepper. If time allows, allow the soup to stand for an hour or more before serving to develop flavor. Heat through as needed before serving.
