1 (1-oz.) pkg. vanilla sugar-free instant pudding mix
1 (1/2 oz.) container sugar-free lemonade drink mix (such as Crystal Light)
4 packets sugar substitute
2 3/4 c. fat-free milk
1 (8-oz.) container fat-free frozen whipped topping, thawed
2 (9-inch) graham cracker crusts
1 tsp. grated lemon rind (optional) two recipes)

Combine first 3 ingredients in a medium bowl, stirring well. Add milk, beating with a wire whisk until thickened; gently fold in whipped topping. Spoon mixture evenly into crusts. Garnish with lemon rind, if desired. Cover and chill at least 3 hours or freeze at least 8 hours. Yields 16 servings. This recipe makes two pies. Chill one, and freeze the other one for later.
