Pour a tablespoon of olive oil in a non-stick pan and place it over medium heat. Then add the chopped onion. Gently fry the onion for about 8 minutes until it is soft and a little brown.
Peel the eggs and chop them up finely. Add the egg to the onion together with the chopped parsley. Season with pepper and salt. Stir well.
Pour the remaining olive oil in a large non stick pan and place it over medium heat until hot. Then add the stuffed squid. Fry it on both sides for about 7 minutes until the squid is cooked through.
