Preheat oven to 400. Scrub your potato clean and wrap in tin foil
Bake for about an hour, until your potato is soft and cooked through. This depends on the size of your potato and the temperature of your oven
Meanwhile, slice your spinach into ribbons and mix together with the greek yogurt and spices
Once the potato is cooked through, slice it down the centre and scoop out the potato. Combine with your greek yogurt mixture and spoon back into the potato shell
Top with parmesan cheese and broil for about 4 minutes until bubbly
