Preparation
Preheat oven to 350 degrees. Grind ginger snaps in food processor. Lightly spray a glass pie pan with cooking spray. Pat cookie crumbs into the bottom of the pan evenly.
Mix the rest of the ingredients in a medium sized bowl and pour into the crust. Bake until knife comes out clean from center, about 45 minutes. Refrigerate and slice in 8 wedges.
Optional: serve each wedge with fat free whipped cream.
