Directions

1. Combine 1 cup flour, sugar, dry yeast and salt in a large mixer bowl and stir until blended. Combine water and 2 teaspoons olive oil in a small microwave-safe bowl.  Microwave on HIGH in 15 second increments until very warm but not hot to the touch  (120° to 130°F). Add to flour mixture with egg white.
2. Beat 2 minutes at medium speed of electric mixer, scraping bowl occasionally. Add 1/2 cup flour; beat 2 minutes at high speed. Stir in just enough remaining flour so that the dough will form into a ball. 
3. Knead  on lightly floured surface until smooth and elastic and springs back when lightly pressed with 2 fingers, about 6 to 8 minutes. Cover with a towel; let rest for 10 minutes.
4. Cut dough into 12 equal pieces. Roll each piece of dough into a 10-inch rope. Spray hands or counter with cooking spray, if dough is too sticky to handle easily. Place on large greased  baking sheet (or use 2 smaller baking sheets, if needed).  Brush with 1 tablespoon olive oil and sprinkle with desired toppings.  Cover with towel; let rise in warm place  until doubled in size, about 30 minutes .
5. Bake at 450ºF for 10 to 14 minutes or until golden brown. Remove from pan with a metal spatula.  Serve warm.
