Cheese and Walnut Pies with Grana Padano and Thyme

In a bowl, mix the eggs with the cream, ricotta and grated Grana Padano, salt and pepper. Add the coarsely chopped walnuts and thyme leaves; mix well. Line 4 pie moulds with the shortcrust pastry, fill with the cheese and walnut mixture and bake in a preheated oven at 180°C for 20-25 minutes. Serve the pies as soon as they have cooled slightly.
