This is a perfect fall dessert. Comes together quickly. From http://www.theviewfromthegreatisland.com

Ingredients
For the pie crust
1 1/4 cups all purpose flour
1/2 cup (1 stick) unsalted butter, cold
1/2 tsp salt
1 tsp granulated sugar
1/4 cup ice water

For the apple filling
2.5-3 medium-large apples, sliced and peeled
2 Tbsp brown sugar
1/2 tsp ground cinnnamon
1/4 tsp ground nutmeg
1 pinch salt
1 Tbsp honey (plus extra for drizzling over the finished galette, if desired)
1 Tbsp unsalted butter, cold or room temp, cut into small pieces

Instructions
For the pie crusts
To make the pie crust, add the flour, butter, sugar and salt to the bowl of a food processor. Pulse several times until the butter is broken up and no large pieces remain.
Slowly add the ice water through the top of the food processor and continue to pulse until the dough comes together in a single lump.
Remove the dough from the food processor. Roughly shape into a disk about an inch thick. Place in the fridge until ready to roll out for the galette.

For the galette
Preheat oven to 375F and line a large baking sheet with a piece of parchment paper.
Toss the sliced apples with the brown sugar, spices, and salt. Set aside.
Sliced apples for apple galette
Place the pie dough on a lightly floured surface, and roll it out into a large circle about 14 inches in diameter. It should be fairly thin, but not too difficult to handle without tearing.

Rolling out galette dough
Gently move the rolled out dough to your prepared baking sheet. Put about half of the sliced apples into the center of the circle of dough, and spread them out evenly, leaving about 1 and a half inches of space all around for folding the dough over the apples. You can simply place all the apples into the center of the dough and spread them out evenly, or you can take the other half and arrange them in an overlapping circular pattern.

Drizzle 1 Tbsp of honey over the apples and dot with the butter. Fold the excess pie crust over the filling.

Lightly brush the edge of the pie dough with milk or cream, and sprinkle with coarse sparkling sugar, if desired.
Place the galette in the oven and bake for about 40-45 minutes until the pastry is golden brown and the apples are cooked through.
