Pre- heat your oven to 375 F. Take the dough out for just few minutes before rolling. Use some dry flour and roll out your dough, rotating it every few rolls to keep it from sticking. It would be little bit hard to roll at first, but it will come along. Stop when it's about 10 or 11 inches in diameter, or when it's at a thickness that is preferred by you. I prefer very thinly rolled but enough that it can hold the filling.
At any given point, your dough starts sticking too much. You can place it in the refrigerator for few minutes after forming the disc.
Add your almond halva filling. Spread it in an even layer in the middle, leaving sides open. I prefer 1-inch top crust. If you like more top crust, you can leave about 2 inches from disc and keep a broader border.
Place your thinly sliced pears in any shape or pattern you desire. Fold sections of dough on top of the filling, creating a tight seal. This is fun part as you can fold it anyways you like.
You can egg wash the borders of the dough or use cream if you do not eat eggs. I used milk to wash the sides of the crust of the dough. Sprinkle with little bit of granulated cane sugar, almonds and pistachios.
Bake your galette – Place the galette with parchment paper lined baking tray in the oven for 30 to 40 minutes, until your crust is a deep golden brown. You want the crust to be golden brown for that flakiness.
Remove it from the oven once it baked. Let it cool on a wire rack.
Slice it in triangles and serve it with side of ice cream or crème fraiche, or whipped cream. I also made a small batch of caramel to serve it with.
