In a large saucepan add the slurry, a heaping cup of strawberries, and sugar and cook over low-medium heat for 4-5 minutes, stirring frequently, I use a potato masher to slightly mash some of the berries to create more of a sauce
Add the remaining strawberries and slice them in half or quarters so they are smaller, more bite-size pieces, and mix to combine. Pour strawberry filling into the pie crust and spread it into an even layer.
