Preheat oven to 450 degrees F (232 degrees C).
In a small bowl, combine the first 13 ingredients to make the spice mix. Toss the spice mix with the chicken thighs and place in a single layer on a rimmed baking sheet. Place the chicken on the top rack of the oven to bake for 25 minutes.
Once the chicken is in the oven, in a 2 qt. sauce pan add 2 tsp of coconut oil and heat over medium high. Add the rice, tossing in the oil to coat. Toast for 2 minutes, stiring constantly. Add the coconut milk, sugar, salt and water. Bring to a boil, stir, cover and drop the heat to a simmer for 20 minutes.
While the chicken and rice are cooking, prep your plantains by trimming off the ends and slicing through the peel from one end to the other. Gently peel back the peel with your fingers and slice the plantains into 1/2 inch disks.
In a large skillet, heat the remaining 2 tsp of coconut oil over medium heat. Once the pan is hot, fry the plantains for 2 minutes on each side until golden brown. Remove to a paper towel to drain.
Once the water has fully fully cooked, remove from the heat and allow to sit for 5 minutes. Fluff with a fork.
Once the chicken has fully cooked, remove from the oven and let cook for 5 minutes. Slice the chicken and sqeeze a half of a lime over the top.
Serve a scoop of rice, cooked plantains, and chicken in a bowl with additional lime slices.
