Spinach, ricotta and sun-dried tomato tart

This is one of those recipes that packs a punch but actually requires very little effort!

1 pack of frozen puff pastry cases
200g of chopped fresh or frozen spinach 
200g of ricotta cheese
1/2 cup grated parmesan cheese
5-6 pieces of sun-dried tomatoes preserved in oil
1 egg (for the egg wash)
1/2 tsp nutmeg powder
Salt
Ground black pepper

• Preheat the oven to 220C.
• Place the spinach in a microwaveable container, add 1 tbsp of water, cover with cling film and steam in the microwave for about 6-7 minutes until the spinach is cooked. Remember to prick the cling film to allow the steam to escape. If using frozen spinach, follow the pack instructions to cook it.
• Allow to cool slightly and remove as much water as possible by pressing it between your hands or in a mesh strainer.
• Mix it with the ricotta cheese, parmesan, nutmeg and chopped sun-dried tomatoes. Season to taste with salt and ground pepper.
• Place the frozen puff pastry in a baking tray and prick the centre area with a fork to prevent it from puffing up. 
• Make an egg wash with the beaten egg and little water or milk.
• Brush the pastry cases with the egg wash.
• Place a tablespoonful of the spinach and ricotta mixture in the centre of each of the pastry cases.
• Cook in the oven for 16-20 minutes till golden brown.
• Serve warm.

This is sufficient quantity for 6 tarts.
