Sprinkle whole-wheat pizza dough with poppy seeds for breadsticks in a flash.
Preheat oven to 450 degrees F. Roll pizza dough on a lightly floured surface into a rectangle roughly 18 by 6 inches. Cut crosswise into 1-inch strips. Twist each strip gently and arrange on a lightly oiled baking sheet.
Blend egg white and water with a fork; brush lightly over breadsticks. Sprinkle with poppy seeds. Bake until browned, 10 to 15 minutes. Serve the same day.
