To make the crust, dissolve the yeast in the warm water in a large bowl. Add the flour, salt, oregano, oil and 1 cup water. Mix well. Knead the dough on a lightly-floured surface for about 2 minutes, or until the dough is smooth. Place the dough in an oiled bowl. Cover with a damp towel and let rise in a warm place for 1 hour, or until doubled in bulk. Punch down the dough. Divide into two parts. Press half the dough onto the bottom of a 10-inch oiled pie pan., sprinkle the Cheese and Broccoli over the dough. Press the other half of the dough into a 10-inch round. Set on top of the Cheese and Broccoli. Crimp the edges together. Make several slashes in the top crust. Bake in a 400 °F oven for 20 to 25 minutes, or until golden brown. Remove from the oven. Spread on the pizza sauce. Bake for 5 minutes.
