Break the eggs into a bowl, add salt and chilli pepper and whisk lightly together, just enough so that the yolks combine with the whites.
Heat a stainless steel frying pan for a minute or so on medium-heat, then add olive oil and butter, allowing it to melt.
Immediately add onions and potatoes and sauté for 7-10 minutes till they are caramelised and look bronze.
Pour in the egg mixture and let it sit, without stirring, for 20 seconds. Stir till the eggs are at the point of setting and resemble a soft custard. Make sure to keep scraping the bottom and sides of the pan.
Serve atop crusty bread (bruschetta) immediately; while warm and creamy.
Adorn with chives or herb of your choice.
