Heat the coconut oil in a large pan over medium heat.
Add the ground turmeric, mustard seeds, and salt & pepper. Stir for 2 minutes, or until the mustard seeds start to pop.
Add in the onion, garlic, and chili, and cook until the onion is translucent.
Add the yellow split lentils and vegetable stock. Then stir and cook gently for 45-50 minutes, stirring occasionally. You can add more water if needed.
Add 1/2 cup coconut milk just before serving, and stir through.
Garnish with a sprinkle of garam marsala, chili flakes, and fresh parsley.
Notes
To reduce overall cooking time, you can soak the lentils overnight/8 hours before starting.
