Combine the water, sugar, and yeast in a large bowl. Let it stand for 10 minutes or until the yeast is bubbly.
Add salt to the mixture and stir.
Add 1½ cups of flour and mix well.
Gradually add more flour until the dough starts to pull away from the sides of the bowl and barely sticks to your finger–usually 3-4 cups depending on your elevation and humidity.
Spray a metal or glass bowl with cooking spray, and place the ball of dough in it.
Remove the dough from the bowl and place it on a floured surface.
Place a Silpat sheet on a baking pan and coat with cooking spray.
Gently roll the dough into a rectangle, then cut it into 20 strips with a pizza cutter.
Twist the dough or wrap it around your finger, then place each twisted breadstick onto the baking sheet. Repeat with the remaining dough, leaving room between each breadstick.
Cover the baking sheet with a tea towel and let the dough rise for another 30 minutes.
Preheat the oven to 425 degrees.
When the bread is finished rising, bake for 9-10 minutes or until golden brown.
Rub the tops of the breadsticks with butter, then sprinkle with garlic salt and Parmesan cheese to taste. Enjoy.
