Cut 3 potatoes (peeled & washed) into small ¼ inch (.635 cm) pieces, roughly chop 1 green bell pepper and roughly dice 1 large onion
Heat a large nonstick fry pan with a medium to medium-high heat and add in ½ cup extra virgin olive oil
After 2 minutes add in the diced onion and chopped green bell pepper, mix with the olive oil, after 5 minutes and the onions are translucent, add in the chopped potatoes, mix together so all the potatoes are coated in the olive oil, mix every 3 to 4 minutes so everything is evenly cooking
In the meantime, crack 6 eggs into a large bowl, season with sea salt & black pepper, whisk together until well mixed, set aside
About 20 minutes after adding the potatoes into the pan, they should be fully cooked through, you can always pierce them with a toothpick to ensure they´re done, remove from the heat and transfer everything into the bowl with the whisked eggs, season the potato mixture with a pinch of sea salt and mix together until well mixed, let the mixture rest for 5 minutes
Heat the same pan with a low to low-medium heat and add in 1 tbsp extra virgin olive oil, swirl it around so it evenly coats the entire surface of the pan
Add the egg & potato mixture into the pan, make sure it´s all in a flat layer, after 2 minutes run a spatula through the outer egdes of the pan to ensure the egg mixture is not sticking to the pan
After 4 to 5 minutes it´s time to flip the omelette, grab a plate that is a bit smaller than the pan, place it over the pan, place one hand on the plate and with the other hand flip the pan into the plate in one swift move, then slide the omelette back into the pan, compact the omelette with a spatula from the outside towards the center, this gives it that classic rounded edge
After a total cooking time of 9 to 10 minutes, that´s 4 to 5 minutes per side, the omelette should be perfectly cooked, you can always pierce the middle with a toothpick, if it comes out cleanly it´s ready to go, remove from the heat and slide into a serving dish, serve warm or at room temperature, enjoy!
