What You'll Need:
2 packages (4-serving-size) sugar-free lemon gelatin
2 cups boiling water
1 cup ice cubes
2 cups frozen light whipped topping*, thawed
What To Do:
1. In a large bowl, dissolve gelatin in boiling water; add ice cubes and stir until melted.
2. Add whipped topping; fold together gently. Pour into a 9-inch deep-dish pie plate. The whipped topping will naturally separate from the gelatin once poured into the pie plate, creating a top layer.
3. Cover, and chill at least 3 hours, or until set.
