For the spinach pancakes, make a thick batter with flour, yogurt, egg, salt and water and fry in oil.
Fry the chopped onion in clarified butter, add the defrosted spinach and cook with the spices (salt, nutmeg, pepper).
Fill the pancake with the spinach, fold and sprinkle with cheese. Bake in a hot oven for about 5-10 minutes until the cheese has melted.
