Pour 1-2 Tbsp of olive oil into a small, non-stick frying pan (aprox. 9-10 inches) and heat on medium heat. Be careful not to get the pan too hot because the oil will burn - or the tortilla will! When hot enough, stir the potato-onion mixture once more in the bowl and pour into the pan, spreading evenly over pan. You may need to turn heat to medium-low heat. Allow the egg to cook around the edges. Then, using a spatula, carefully lift up one side of the tortilla to check if the egg has slightly browned. The inside of the mixture should not be completely cooked and the egg will still be runny on top and in middle.
