In this recipe, two favorite desserts -- pudding and pie -- are combined in one, for the ultimate in sweet comfort food. It's the ultimate in ease, too, thanks to frozen puff pastry dough as the crust (instead of pie dough from scratch). The filling is made with pudding mix, another viable shortcut, with port imparting grown-up flavor. In all, it only takes about an hour to serve up a slice of bliss.
