In a mixing bowl, combine flour and salt. Add cold butter and mix until crumbly.

Gradually add ice water, mixing until dough forms. Shape into a disk and refrigerate for 30 minutes.

Roll out the dough on a floured surface and fit it into a 9-inch pie pan.

In a saucepan, combine sliced strawberries, sugar, cornstarch, lemon juice, and vanilla extract.

Cook over medium heat until the mixture thickens and bubbles, about 5-7 minutes.

Pour the filling into the prepared pie crust.

Preheat the oven to 375°F (190°C).

Bake the pie for 30 minutes or until the crust is golden brown.

Let the pie cool before serving.

Slice the pie and serve with whipped cream on top.
