Preheat the oven to 425 degrees.
Season the chicken with salt and pepper to taste
Combine the olive oil, serrano, garlic, all spice, nutmeg, cinnamon, ginger paste, sugar free honey and lime juice in a bowl, and stir to combine into a paste.
Spread the paste over all sides of the chicken pieces, and under the skin if possible.
Add the chicken to a well greased 9x13 baking dish, and sprinkle the onion around the chicken pieces.
Bake for 45-50 minutes, or until the chicken is cooked completely through.
Garnish with green onions, and serve with cauliflower rice if desired.
