Cook in hot oil at medium heat 1 chopped onion and 1 finely chopped garlic clove. Cook until the onion is soft. Gradually add 600g spinach and cook until the leaves are wilted completely but still bright green. Add 2 tablespoons finely chopped basil. Then turn out the heat and add 250g ricotta, 50g grated cheese, 1 beaten egg and season it with nutmeg, salt & pepper. Line in a greased tin with puff pastry. Fill the tin with the spinach ricotta mixture. Scatter some grated cheese over it and place the tin in a preheated oven (200C fan) for about 25 minutes. Enjoy!
