Lentil Soup from Jordan

Warning: This soup is very ugly, and very delicious.

1 cup lentils
1 potato, peeled and diced
1 onion
1 8 oz. can tomato sauce
1 Tbsp cumin
1 lemon

Boil lentils, potato and onion until potato is soft (about 20 minutes). Remove from heat and let sit five minutes. Blend until smooth and put back in pot. Add tomato sauce and spices and water if it needs it. Heat through for 5-10 minutes or whatever. Serve with lemon slices to squeeze over soup.

Variation: use ½ Tbsp curry instead of cumin
