Pour the filling into a 13x9-inch baking dish, and bake in 400° F oven for 18 minutes. Remove the dish from the oven (keeping the oven on and close the door behind you), and stretch the defrosted puff pastry over the top of the filling, gently folding some of the pasty over the sides of the pan. Using a sharp knife, cut 3 slits in the top of the puff pasty to allow steam to escape. Return the baking dish to the oven and bake for an additional 10 minutes, until the puff pastry is golden brown and the filling is bubbly. Allow to cool for 5-10 minutes before serving.
