Mash the potatoes coarsely and stir in a beaten egg.
Mix together a finely chopped onion sauteed in olive oil, a large pinch each of dried and ground chilli, coriander and oregano plus a good pinch or two of sea salt and black pepper. Add the seasoning to the potatoes and fold in with a gentle hand (do not overmix or it will become rubbery). Add enough flour so that the mixture keeps its shape when formed into a ball. If you add too much flour mix in a little water to get the correct consistency.
Form into medium-size balls in the palm of your hand and dip in olive oil. Place on greaseproof paper on a baking tray and flatten to about 2cm high (leaving plenty of space for the next one). Bake in a hot oven (180' fan or equivalent) for 15-20 minutes until cooked through and golden brown on top.
Serve warm as a side dish or with a chunk of good quality cheese.
