Heat the olive oil in a large frying pan over a high heat, or if using an air-fryer, heat to 205C for 3 mins. Fry the peppers, stirring frequently, for 5 mins until blistered and wilted. The peppers should be soft and slightly charred.

Transfer the peppers to a serving plate and season with some sea salt. Serve with dips or as part of a tapas spread, if you like.
