In the bowl of a food processor, add the flour, ½ teaspoon salt, and pulse to combine.
Add 2 tablespoons of Tillamook Sharp Cheddar Shreds and butter and pulse until broken down to the size of Lima beans.
With the motor running, drizzle the water into the flour mixture one tablespoon at a time, pulsing between additions, until the dough just starts to hold together.
Turn out the dough onto a lightly floured surface and shape into a 5-inch disk. Cover with plastic wrap and refrigerate for at least 1 hour, up to three days.
Preheat the oven to 400˚F.
On a lightly floured surface, roll the dough into a 14-inch circle. Transfer the dough to a parchment paper-lined baking sheet.
Spread the remaining 2 tablespoons of Tillamook Sharp Cheddar Shreds on the center of the dough, leaving a 3-inch border.
Add the sugar, cinnamon, and apples, to a medium bowl and toss to combine.
Layer the apples over the cheese. Fold the edges of the dough over.
Brush the border with egg wash and sprinkle with sugar. Bake until golden brown, about 50-60 minutes.
