In a stock pot, use the lo cal spray and heat, add the onion and garlic and gently fry until soft. Add the curry powder and stir in for a minute. Add the rest of the veg and mix together and then pour in the stock, tomato puree and lentils. Bring to the boil and simmer for 20 minutes until the veg are tender. The soup will have thickened nicely, add S&P to taste.
I made two batches of this soup over the weekend, it was that delicious!
