For a topping alternative, use thawed purchased puff pastry dough. Preheat an oven to 425deg.F and lay the dough on top of the filling in the dish. Trim the dough around the dish, leaving a 1-inch overhang. Fold the overhang back over itself and press it into the sides of the dish to make a sturdy rim. Prick the dough with a fork to create steam vents and bake until golden brown.
