Heat oven to 200C/180C fan/gas 6. Use a fork to prick the potatoes all over. Rub with a little of the oil, and bake for 45 mins until tender.
Meanwhile, make the chilli. Heat the remaining oil in a large frying pan over a medium heat. Add the onion, garlic and some seasoning, and cook for 5 mins until soft. Add the turkey mince and season again, then increase the heat and break up the mince with the back of your spoon. When it’s cooked through, add the spices, vinegar, sugar and passata. Reduce to a simmer and cook for 10 mins or until the liquid has reduced.
Cut a cross in the top of each potato and spoon in the chilli. Serve each potato sprinkled with cheese and spring onions.
