1. Add lentils to pot with 4 cups water. Add salt and bring to a boil cook over a moderate heat until all the lentils are cooked. Most of the water should have been absorbed during the cooking time, if not drain the lentils.
2. Take another large pan, and heat the oil on a high flame. Put in the garlic, ginger and cumin seeds. As the garlic begins to brown, add spinach. Stir.
3. Add the spices to the spinach mixture. Mix the cooked lentils and spinch together and add salt, to taste.
This is quite a dry dish and is good with onion raitha. If you like spicy foods, you can add green chilies with the garlic and ginger.
