In a medium sized pot, heat up the coconut oil and add in the onion and season with salt. Sauté for a couple minutes on medium until translucent and then add in the garlic, ginger, turmeric, and curry powder. Sauté on medium low for 3 minutes until the ginger and garlic get cooked through.
Add in the lentils, coconut milk and then fill the coconut milk can with water and pour that in as well. Bring to a boil and cover with a lid, then turn down the heat to low and simmer for 20 minutes until the lentils are tender. Check for seasoning and serve with steamed rice.
