All we need is
For vegetarian version:
2 cups of dry lentils
1 cup of sliced onions
1 stick of celery ( chopped)
1 little carrot ( chopped)
few cloves of garlic
A little bit of yogurt (plain)
Boil the lentils without salt in water until almost done
Fry the garlic, onions, celery and carrots, add a little bit of salt and black pepper. You can add cumin, but not much.
When lentils are cooked, just pour the fried vegetables into the lentils. Mix well. Cook until lentils are done. Let the soup stay for a about 10-15 min. for aromas to mix.
Serve hot.
When the soup is in the serving dish , put one table spoon of yogurt on the top.
You can turn it into a lentil and sausage soup by adding into the fried vegetable mixture a little bit of your favorite smoked salami. I add Polish kielbasa, andouille sausage or smoked chorizo.
So you will get something like this:
