Ingredients:
3 oz reduced-fat cinnamon graham crackers, about 5 1/2 sheets
1 Tbsp packed light brown sugar
2 Tbsp regular butter, melted
2 large egg white(s)
1 large egg(s)
1/2 cup(s) dark brown sugar
1/4 tsp table salt
2 tsp pumpkin pie spice, or less to taste
1 cup(s) canned pumpkin
1/2 cup(s) fat-free evaporated milk
1/4 cup(s) lite whipped topping

Directions:
Position rack in middle of oven. Preheat oven to 350ºF.

Place graham crackers and light brown sugar in a food processor; process into crumbs (or smash into crumbs in a sealed plastic food bag with a rolling pin). Spoon crumbs into a small bowl; add melted butter and combine with fingers into a coarse meal. Distribute crumbs evenly on bottom and up sides of an ungreased 9-inch pie plate. Chill for 30 minutes before baking. Bake until crust starts to turn golden, about 8 to 10 minutes; remove from oven and let cool.

While you are waiting for the crust to cool you can mix up the rest of the ingredients

In a large mixing bowl, using an electric mixer, whip egg whites until frothy; fold in egg, dark brown sugar, salt, pumpkin pie spice, canned pumpkin and evaporated milk. Beat pumpkin custard until smooth and pour into pie shell. Bake until a knife inserted in center comes out clean, about 45 to 55 minutes (we baked at 50 minutes). Slice into 8 pieces.

This is approx 5 weight watchers points and it is every bit as delicious as regular pumpkin pie
