Preheat your oven to 350 degrees F.
Prepare your pie crust in a pie plate, following the package directions or your favorite homemade recipe.
In a large bowl, combine the strawberries, rhubarb, white sugar, and all-purpose flour. Gently fold the ingredients together, ensuring the fruits are evenly coated with the sugar and flour mixture.
Pour the mixture into the prepared pie shell. Spread it out evenly, making sure every inch of the crust is filled with the vibrant filling.
Place the pie in the preheated oven and bake for 60 minutes or until the filling is bubbly and the crust is beautifully golden.
Once baked, remove the pie from the oven and let it cool on a wire rack.
