You can eat these chips on their own, or dip them into applesauce, your favorite nut butter, or even some chocolate hazelnut spread.
In small bowl, use spoon to combine sugar and cinnamon.
Cut each tortilla into 8 wedges and transfer to large bowl. Spray wedges generously with vegetable oil spray. Sprinkle with sugar mixture. Use your hand to gently toss tortilla pieces to make sure they are evenly coated and shiny on all sides. Use more cooking spray if needed.
Spread half of tortilla pieces onto rimmed baking sheet in single layer. Spread remaining tortilla pieces onto second rimmed baking sheet in single layer.
Place both baking sheets in oven and bake until chips are golden and crisp, 10 to 15 minutes. (Note that chips on lower rack may cook more quickly.)
