Wash and peel the potatoes. Cut into half inch cubes.Heat the cooking oil in a non-stick pan. Add the potatoes and pan fry over high heat until the edges are brown.
Pour off the oil. The oil that coats the bottom of the pan is enough to cook the beaten eggs.
Reheat the potatoes. Season with salt and a little ground pepper. Over medium heat, pour in the beaten eggs. When the eggs start to set, stir the mixture a few times. Allow to set once more then stir again. Repeat until the eggs are cooked and firm.
