Start by marinating the chicken. First sprinkle the chicken with salt. Next, make the marinade by mixing 2 tablespoons of lemon juice with 2 tablespoons of olive oil and the garlic.
Place the chicken in a bowl and rub with the marinade. Leave to marinate for at least 30 minutes, but overnight is fine.
When you are ready to cook, preheat the oven to 200˚C. (400˚F)
Heat a frying pan with coconut oil and fry the chicken legs until golden brown. Discard the remaining marinade.
Place the chicken in the oven to roast for about 18-20 minutes. During the last five minutes, add the rosemary sprigs to the pan.
Peel and dice the sweet potatoes. Boil the potatoes, drain and mash with a masher. Season with salt and pepper.
Fry the orange slices in a pan with a little oil until golden brown and caramelized.
Serve the mash with the chicken legs and orange slices.
