Heat the oil in a medium saucepan and fry the onions until soft and golden. Add the mince and brown. Add the Rhodes Quality Mild & Spicy Chakalaka and bring the mince to the boil. Add the potatoes, reduce the heat and simmer gently to heat through. Season to taste. Cool. Use a round saucer or cutter to cut out 12 rounds of pastry. Spoon a tablespoon of the Chakalaka mince on to the middle of each pastry round. Brush the edges with the egg. Close the circle to a semi-circle over the top of the mince and press the edges together to seal the filling inside. Place the pasties on a baking tray lined with baking paper. Bake in an oven preheated to 200° for 20 minutes, or until the pastry is golden and cooked through. Serve hot.
