Here's a very simple yet healthy and delicious way to eat your greens. Serve this warm with rice or Indian roti for a complete vegetarian meal.
Heat the oil in a pan over low heat. Add the mustard seeds, cumin seeds, and red chiles and fry until the mustard crackles, for 1-2 minutes. Add the onions, Thai chile, garlic, ginger, and a little salt, and cook until browned slightly.
Then, add the turmeric and asafoetida powder. Next, add the spinach and stir well to combine. Add the cooked lentils and cook for 3-4 minutes. Remove from the heat and serve warm with rice or roti.
