Soften the yeast in the water. Add salt and vegan sugar. Stir well. Add wheat flour and cornmeal plus two cups white flour (until dough isn't sticky). Knead in the rest of the flour, add more if necessary to make a stiff dough.
Let rise for 5 minutes to 1/2 hour (depends on how much time it takes to cut toppings). Cut dough in two, roll out to fit pans. Sprinkle the pans with cornmeal to keep dough from sticking. Top and bake at 400 degrees for 12-15 minutes.
