Wash the lentils and rice well and rinse, then add to a pot with water, bringing to a boil. Lower to a simmer and cook until soft, about 30 minutes or so. Throw in the carrots (if you choose to use them).
When the lentils and rice are almost cooked through, heat the coconut oil in a separate pan. Add the mustard seeds, allowing them to “pop” and burst open for a few seconds, as you mix them. Then, add the cumin seeds, onion, garlic, cooking until soft.
Stir in the turmeric and coconut milk until heated, then add the lentils, rice, and carrots. Then, stir in a generous handful of spinach until soft.
Combine and season with sea salt. Adjust seasonings as desired. Enjoy!
