Line a baking sheet with parchment paper or silpat.
In a food processor or blender, combine sugar, cinnamon, cranberries and pecans. Pulse until the filling is well chopped but not too fine. (You want some larger pieces of nuts and cranberries.)
Unfold the puff pastry sheets and divide filling between both sheets.
Fold the left and right sides to meet in the middle of the puff pastry.
Fold the left over the right completely.
Place the folded pastry logs on the baking sheet and chill at least 30 minutes.
Preheat the oven to 425.
Remove puff pastry from the refrigerator and slice 1" thick slices.
Place the pastry slices on the sheets, filling side up.
Bake for 20 minutes, flipping pastries half way through.
Bake until pastry is golden brown and filling has caramelized.
