In a large bowl combine the yeast and 1/2 cup of the warm water. Stir and let sit for 5 minutes.

After letting the yeast stand add the flour, salt, and sugar to the
bowl.  Mix by hand or use a stand mixer with a dough hook and mix 1-2
minutes. 

Add in the remaining water and melted butter and continue mixing until
everything is well incorporated.  Then, either mix on medium speed for 5
minutes or turn onto a floured surface and knead the dough for 5
minutes until it is smooth.

Spray a separate bowl with cooking spray.  Put the dough ball into the bowl, turning to coat with oil.  Cover with plastic wrap and then a kitchen towel and let sit in a
warm area for 1-2 hours or until doubled.

After doubling turn the dough onto a lightly floured table and roll
into a 12 x 12 square.  Brush with the softened dough and sprinkle with
oregano.  Begin rolling the dough into a tight cylinder.  Place the
dough seam side down and push down to flatten.  Fold the dough into
thirds like you are folding a letter pinching the ends to form a ball. 

Put the dough back into the bowl and cover with plastic wrap. 
Cover and let rise 1-2 hours on until doubled in size.

Divide the dough in half.  Wrap half in plastic wrap then place in a freezer bag.  Freeze for later.  Roll the remaining half into a 10 inch circle.  At this point
preheat the oven to 500 degrees.

Spray the sides of a 9 inch springform pan with cooking spray. 
Put the dough circle in the springform pan and press against the bottom
and sides of the pan.  Pour the meat and veggie toppings on the bottom
and cover with 1 cup of the cheese.  Heat in the oven for 15 minutes.

After 15 minutes reduce oven temperature to 400 degrees.  Remove the pizza from the oven and cover with the sauce, then top with remaining cheese.  Bake for an additional 10-15 minutes or until crust is golden brown.  Remove from oven and let
cool 5 minutes.  Remove from springform pan and let cool an additional 5
minutes.  Cut into slices and serve hot.
