How to cook
Peel and slice the potatoes. Preheat the oven to 392°F (200 degrees) and grease a baking pan.
Boil the potatoes, strain and mash them. In a deep bowl, mix the potatoes with the spinach, cream, butter, spring onions, black pepper and salt.
Transfer the mixture into the baking pan, bake it for 15 minutes. Sprinkle it with cheese and bake it for another 5 minutes.
