1. Combine Strawberries and Pudding Mix:
- In a large bowl, combine the thawed, sweetened sliced strawberries (with their juices) and the instant lemon pudding mix.
2. Let Stand:
- Let the mixture stand until slightly thickened, about 5 minutes. This allows the pudding mix to begin to set.
3. Fold in Whipped Topping:
- Gently fold in the thawed whipped topping until well combined.
4. Pour into Crust:
- Spread the strawberry-lemon filling evenly into the graham cracker crust.
5. Freeze:
- Freeze for at least 8 hours, or preferably overnight, until completely firm.
6. Let Stand Before Serving:
- Let the pie stand at room temperature for 5-10 minutes before serving. This makes it easier to slice.
7. Garnish (Optional):
- If desired, serve with additional whipped topping and fresh strawberries.
