Step 2Place the lentils in a pot with 3 cups of water and bring to a boil, skimming off any foam that develops on top. Reduce the heat and add the carrot, onion, squash, salt, cumin, garlic and turmeric. Partially cover and cook over low heat until the stew is thick and the lentils are soft, 45 to 60 minutes. Garnish with the parsley or cilantro and serve.
