In a large pot over medium-high heat combine the lentils and 6 cups of water. Bring to a boil, then add the spinach, ginger, turmeric, 3/4 of the green chiles, and all of the tomatoes. Reduce the heat, and simmer for 1 1/2 to 2 hours or until the lentils are extremely soft. You may need to add a bit more water during the cooking process to keep the lentils soupy.
