Heat coconut oil in large pot. Add onion, garlic, and ginger. Season with salt and pepper and cook over medium heat until translucent, about 3 minutes.
Add rice, split peas, and curry powder. Add 1 can of light coconut milk. Reduce heat and simmer until coconut milk is absorbed, about 10 minutes.
Once the coconut milk is absorbed, add the second can of coconut milk, water, and spinach. Simmer until liquid is absorbed and rice is fully cooked, about 30 minutes.
