Kumpir (stuffed baked potato)

Instructions

1. Preheat the oven to 200 °C. Wash the potatoes, prick them with a fork and rub them with a little oil and salt.
2. Place them directly on the oven rack and bake for 50 to 60 minutes, until the skin is crispy and the flesh gives way under a knife.
3. While they bake, prepare the toppings: thinly slice the onion, dice the tomatoes and cucumber, drain the olives and sweetcorn.
4. Take out the potatoes and cut a cross on the top. Lightly mash the flesh with a fork.
5. Add a knob of butter and some salt to each potato, then pile on the grated cheese, which will melt from the heat.
6. Arrange the toppings on the side, drizzle with mayonnaise and ketchup, then serve straight away.
