Boil the lentils and stock (or water) for 30 minutes in a soup pot. Once tender, put half the lentils and some of the stock in a blender. Blend until puree'd. Add puree'd mixture back to soup pot with whole lentils. Empty bottle of Tikka Masala Sauce and bring to boil. Add water to preferred soup consistency. Add salt to taste if needed. Serve with chopped fresh tomatoes and toasted bread.
