Cover the frying pan with a lid or plate and allow the potatoes to cook gently for 20 minutes until soft but not falling apart, stirring several times during cooking to ensure they are not sticking and adding a little water if they are
Meanwhile beat the eggs in a large bowl, then add chopped chives and salt
Add the cooked potatoes to the beaten eggs and gently mix
Add the remaining tablespoon of olive oil to the frying pan and keeping it on a low to medium heat return the potato and egg mix to the pan
After about 10 minutes, when the omelette is starting to look set at the sides cover the frying pan with a large plate and invert the pan, tipping the omelette onto the plate then carefully slide it back into the frying pan to cook for another 5 minutes
Serve in slices as part of a tapas style meal
