Azizi...when my mother made pie crusts, she always used the leftover bits to do as you said...sprinkle sugar & cinnamon on them and bake them (rather than fry them, since she was baking anyway)...VERY occasionally she would put a bit of jam on bigger pieces and make turnovers, but the simple sugar/cinnamon ones were the staple!

In recent years I have cajoled my wife to adopt this practice...though we don't have pie that often....and my mouth still waters when those cinnamon sugar treats are ready.

I do remember sitting at a table during a storm (in New Orleans!) about 1946-7, eating potato soup made with bacon bits chopped into it and thinking there was no better treat in the world! It was many years before I learned that potato soup was what we ate when money was short....(these were the days when cheap hamburger was an occasional cat food, as there was not much in the way of commercial pet foods)
