Preheat oven to 350 degrees F.
Place the yeast in a large mixing bowl, and add water. Set aside.
Chop and prepare all your toppings.
Make the dough. Combine all dough ingredients with the yeast mixture. Knead until you have a nice firm ball of dough. Let stand, covered with a towel, for about 10 minutes.
When the dough has set, spray a cookie sheet with a light coat of olive oil spray, and press the dough out until it covers the cookie sheet. This may take a few minutes.
Place in your preheated oven for about 15 minutes, or just until dough is cooked through. Try not to let the edges brown. It may help to lightly lay some aluminum foil over it as it bakes.
Make the sauce. When the dough is finished baking, remove it from the oven, and spread the sauce over the crust. (Careful, the pan is hot!) Distribute your veggies evenly over the sauce and dough, and return the entire thing to the oven. Bake for approximately 20 - 30 minutes, or until vegetables are cooked. Again, you may want to use some foil over the top as it bakes to keep the edges of the dough from getting to brown.
When the pizza is finished baking, remove from oven, allow to cool slightly, sprinkled with parmesan and cut into twelve pieces.
Bake the crust for 10 minutes. Cool completely. It's best to freeze the dough without any toppings. But if you really want a "ready-to-go" pizza, add all toppings except the basil and tofu (if using). Cover with plastic wrap and freeze for up to 3 months.
