Preheat oven to 350 degrees F.
In a bowl, combine warm water, yeast and sugar. Lightly stir, then set aside and let sit for 5 minutes until frothy.
In a large bowl, combine 2 cups of flour, sugar, nonfat dry milk, and salt and mix until well combined.
Add in shortening and work into the dry ingredients until it is crumbly in appearance.
Add water and yeast mixture along with egg to the dry ingredients and begin mixing.
Gradually add flour one cup at a time to form a soft dough. Once all flour has been added, continue kneading or mixing for another 2-3 minutes. When done, the dough should be slightly sticky to the touch.
Cover the dough with a towel and let rise until double in size.
Once dough has risen (about an hour), generously flour a surface on the counter and scape the dough out of the bowl and onto the floured surface.
Knead a few times, then set aside.
Generously spray two large baking sheet pans with cooking spray and set aside.
Pinch off a palm-sized piece of dough and roll it into a long, thin rope. Fold the rope in half, then gently twist the two ends together to form a spiral, and place on a baking sheet.
Repeat this process until all breadsticks have been made.
Bake for 8-10 minutes until breadsticks are golden brown.
Remove from heat and let cool.
Serve and enjoy!
