In a small bowl, add sugar, yeast and warm water. Allow to sit for 5 minutes so yeast are bubbly.
In a large bowl add all dry ingredients. Whisk to blend.
In the bowl of yeast and water, add olive oil. Pour into dry ingredients and mix.
Shape the dough into flatbread, cover it with plastic wrap, and let it rise in a 200º F warm spot for 45 minutes.
Preheat the oven (or grill) to 425º F. If your pizza stone is new and not seasoned yet, put a thin layer of olive oil. Put the pizza stone in the oven while preheating so it gets nice and hot. Remove the stone from the oven. *See note*
Break pieces of dough off. Put a piece in between two pieces of plastic wrap. Roll to ½ inch flat for pizza or ¼ inch flat for a thinner flatbread. Carefully put on the pizza stone.
Bake for 8-10 minutes until the crust is crispy.
If you are adding toppings, remove the crust from the oven and spoon sauce onto the crust. Top with mozzarella cheese. Add your favorite toppings.
Bake an additional 5-8 minutes until the cheese is melted.
