A galette is a french pastry that can be sweet or savory.  They often have a rough country look, so don't fret too much about appearances.  This one is topped with apples and would be fantastic with ice cream.  
4-5 Tbsp sugar
1/4 tsp salt
6 Tbsp butter, chilled and cut into pieces
5 crisp apples
1 tsp ground cinnamon
1/4 cup lemon juice
Heat oven to 400 degrees.  Combine flour, 1 Tbsp sugar and salt, and cut butter into mix until it resembles course crumbs.  Slowly add 3-4 Tbsp ice water until the dough just comes together.  Gently press the dough into a disc and refrigerate until firm, about 30 minutes.  
Peel, core and roughly chop 2 apples.  Heat on medium the apples, 1 Tbsp sugar, 1/2 teaspoon cinnamon and cook, stirring occasionally until the apples are tender and the mixture is the consistency of chunky applesauce (about 15 minutes).  Add 1/4 cup of water if the pan gets too dry while the apple mixture is cooking.  Take the mixture off the heat and cool.  Once cool, stir in 3 Tbsp lemon juice and set aside.
On a lightly floured surface, roll chilled dough into a 12-inch circle, about 1/8 inch thick.  Sprinkle the dough with remaining tablespoon of sugar and prick the dough with a fork several times to prevent puffing.  Pre-bake until dough is just starting to set, about 8-10 minutes.  Remove from heat and cool.
Core remaining apples and cut them into slim, even slices.  Toss the apple slices in a bowl with 1 Tbsp lemon juice, 1/2 tsp cinnamon.  Spread dough with cooked apple mixture, leaving a 1/2 inch border.  Arrange apple slices over mixture in a spiral pattern, slightly overlapping each piece. Sprinkle the top with 1-2 Tbsp sugar.  Bake until crust is golden brown and cooked through, about 30 minutes.
