Chop sweet potato into desired size, toss with ½ tablespoon of olive oil, and sprinkle with a pinch or two of sea salt, a dash of cinnamon, and about ¼ teaspoon of onion powder. Place the sweet potatoes on a parchmentlined baking tray and roast for 30-35 minutes in a 400 degree oven. Dry toast your pecans and coconut flakes over low heat in a pan for about 5 to 10 minutes, or until fragrant. Once they are done, remove them from the skillet and warm a very small glug of olive oil over medium heat to wilt the spinach.
When the spinach is nearly wilted to your liking, add the sweet potatoes to the skillet and stir to combine. Serve the sweet potato/ spinach mixture over brown rice and top with pecans, coconut, and tahini dressing. Note: you can toss the sweet potato-spinach mixture with a drizzle or two of the tahini dressing before serving over brown rice. Or just serve on the side so that you can add as you please. (This dish would be a delicious bed for grilled chicken also.)
