In a sauce pan,
3 tablespoons of olive oil,
2 chopped onions,
2 chopped carrots,
2 chopped medium potatoes
clove of garlic
Saute till soft (10-15 minutes), add 4 tablespoons of curry powder and 1/2 teaspoon of cayene pepper (more if you dare) and cook for a few minutes.
Add a can of chopped tomatoes (or 6 to 8 fresh tomatoes already stewed) and a 900 ml container of low sodium chicken broth and 2 cups of washed green lentils. Bring to a boil, then simmer for up to 2 hours.
It is a bit thick so you may add some water.
