Preheat oven to 375 degrees F. Roll out the crescent roll dough and separate each crescent. Take the pumpkin pie filling and place 1 tsp. of pumpkin pie filling onto the bottom of each roll. (you can freeze the rest of the pumpkin pie filling for another dessert if desired). sprinkle a few pecans on top of the filling and then roll each crescent up normally. Sprinkle a little brown sugar and pecans on top of each roll and then press the pecans lightly on top to make sure they stick. Bake for 8 minutes or until lightly browned.
