Preheat oven to 450°F. Combine flour, sugar, cinnamon, ginger and nutmeg in large bowl. Add pumpkin, evaporated milk and Egg Beaters; beat with wire whisk until well blended. Pour into crust.
Bake 20 minutes. Reduce oven temperature to 350°F. Bake 35 minutes more or until knife inserted in center comes out clean. Cover edge of crust with aluminum foil for the last 10 minutes of the baking time to prevent over-browning, if necessary. Cool completely on wire rack.
Top with Reddi-wip just before serving, if desired.
