I always have a little bit of extra dough scraps whenever I make something with dough.
By the way, this is the dough recipe that I use for everything: http://www.landolakes.com/recipe/2092/butter-pie-crust
It's really easy to make. I make it in the food processor. Its enough for 2 pies.
This is one of the things that I like to do with the extras:
Roll the dough into a rectangle and brush it with melted butter. Then sprinkle sugar and cinnamon on it. Roll it up and slice it. Put them on a baking sheet and bake them with your pie for about 10 mins or until they start to get light brown.
Here is another one:
I made a quiche and had enough leftover to do a tiny little apple pie. I cut half an apple into small chunks. I added about a teaspoon of flour and a teaspoon of sugar and a little bit of cinnamon. I mixed that and put in the pie crust and drizzled caramel on top.
