- Start by washing the pepper under cold water. Dry the peppers well before cooking. 
- In a large cast iron add a generous layer of olive oil, about 1cm high. Heat the oil slightly. 
- Add the peppers and let them cook until they start to blister. Turn them over until they are equally cooked on both sides.  
- Take out the peppers with a slotted spoon and place on a serving plate. Sprinkle generously with salt flakes and serve!
