Preheat the oven to 400ºF / 200ºC degrees.
Heat the olive oil and butter in a pan then add in the shallots and mushrooms and fresh thyme.
Cook until softened and all the liquid has been absorbed.
Remove from the heat and stir in the cream cheese, parsley and grated parmesan. Season with salt and pepper.
Unroll the pastry and cut into four squares.
Score a border around the edge of each and prick the base several times.
Divide the creamy mushroom mixture between each pastry keeping inside the scored border.
Place in the oven for around 15 minutes until the edges are puffed up and golden brown.
Serve with a crisp green salad.
