Preheat the oven to 350 degrees.
Cut each tortilla into 8 triangles, lay them on a baking sheet, and coat the tortilla triangles with cooking spray.
In a small bowl, spoon 1 tablespoon of the sugar with the cinnamon, stirring well to mix; sprinkle the sugar-cinnamon mixture over the tortilla triangles. Bake for 12 minutes, or until crisp.
Meanwhile, place the strawberries, orange juice, and remaining tablespoon of sugar in a blender container, and blend for 30 seconds, until smooth.
Into individual serving bowls, spoon ½ cup yogurt and top with strawberry sauce. Serve the cooled tortilla triangles on the side for dipping.
