Move an oven rack to the place that is second from the bottom. Preheat oven to 425* F. Line a baking sheet with parchment.
3 Medium Apples, peeled, cored and sliced into ¼" slices, ¼ Cup Brown Sugar, tightly packed, 1 ½ teaspoon Cinnamon, ¾ teaspoon Ground Ginger, 2 teaspoon Cornstarch, Pinch of Salt
In a large bowl, combine sliced apples, brown sugar, cinnamon, ginger, cornstarch and salt. Toss with your hands until well combined.
Lightly flour a work surface then roll the pie dough out into a rough 12" circle. Its okay if its not perfect. This is a rustic tart!
Transfer the pie dough to the parchment lined baking sheet. Then, using your hands, place the apples onto the pie dough, leaving any juice that has been released fro the apples in the bowl. Be sure to leave a 2" border.
Now, add the streusel to the top of the apples. then, fold the border of the pie dough toward the center to create the crust, overlapping itself every few inches to create pleats.
Bake in a 425* on a rack that is second from the bottom oven for 40-45 minutes, until the crust and streusel topping are golden brown.
Serve warm.
