In the bowl of a standing mixer combine the yeast, sugar, and warm water.  Stir together and let sit until the yeast activates and is foamy.  About 5-10 minutes.  If you don't have a packet, use 2 1/4 tsp of yeast.  

With the mixer on, add the salt and olive oil.  Stir in the flour and mix until the dough forms a smooth ball.  

If the dough is too dry, add more water one Tbls at a time.  If it is too wet, add more flour one Tbls at a time.  

Spray a bowl and a piece of plastic wrap with non-stick cooking spray.  Place the dough in the bowl and cover with the plastic wrap.  

Place in a warm area for 1 - 1 1/2 hours (I put mine in the oven with the light on.  If you are in a hurry and want to speed it up, put your oven on it's lowest setting - 100 degrees F.)  

Preheat oven and pizza stone or an upside down sheet pan to 500° Fahrenheit.  Roll or stretch dough out on floured surface.  Sprinkle cornmeal on counter or paddle.  Place dough on top of the cornmeal.  Top with sauce and toppings of your choice.  Brush with olive oil and sprinkle with garlic salt and Italian seasonings.  

Slide pizza off paddle and on to the stone or baking sheet. Bake for 10-12 minutes, until cheese is melted and dough is cooked to your desired level.
