Method

Preheat the oven to gas 7, 220°C, fan 200°C.
Place the potatoes on a plate and microwave on high for 15 mins. Carefully turn over, using a pair of tongs, and microwave for a further 10-15 mins until they are soft in the centre. Cook for a little longer if your potatoes are particularly large.
Once the potato is cool enough to handle, rub the skin with the oil, place on a baking tray and cook in the oven for 15 mins until the outside is crisp. Cut a cross in the top and fluff up the potato inside with a fork.
Meanwhile, mix the tuna and mayonnaise together and season with freshly ground black pepper. Rinse the red onion in cold water, pat dry with kitchen paper, then fold through half the onion, olives, capers, sundried tomatoes and parsley.
When you’re ready to serve, stuff the potatoes with the tuna filling and load with the remaining toppings.
For easy jacket potatoes that are extra crispy, prick the skin, rub evenly with oil and a pinch of sea salt and place in the air-fryer basket. Cook at 200°C for 20 mins, before turning and cooking for another 10 mins until a knife passes easily through the flesh.
