This recipe is best with leftover boiled potatoes, but roast potatoes or mashed potato will work too. Press a fork into the potatoes to break them up a bit, then fry in a little olive oil. Add some cumin, ground coriander seeds and paprika. Push the potato to the side of the pan, so you can break an egg in the middle. Fry both sides, but only for a short while on the second side so the egg yolk will run. Serve with grated cheese and some sweet chilli sauce.
