Place pie dough into a pie pan and using a pastry brush coat the inside and outside of the dough with egg yolk. Bake according to instructions. Remove the crust from the fridge and let cool.

Take half of the strawberries and blitz in a food processor until achieving a smooth consistency. Place the strawberry mixture into a saucepan along with the salt, vanilla extract, lemon juice, corn starch, sugar and orange zest. Bring mixture to a boil and reduce to a simmer. Simmer for 10 minutes, stirring occasionally. Remove from the heat.

Cut the remaining strawberries into bite-sized pieces and stir into the simmering strawberry mixture.

Once the pie crust has cooled fully to room temperature, pour the strawberry filling into the cooked pie crust and chill for 3-5 hours. When serving, top with whipped cream or cool whip.
