First, let's make the dough by combining all of the ingredients in a large bowl. You don't knead the dough that long as you would with regular flour. Just make sure everything is combined.
Next, sprinkle some flour onto the dough and let it rise for about 1 hour, or until it doubles in size.
Meanwhile, combine tomato sauce, garlic powder, oregano, and salt in a small bowl, to create a pizza sauce. If your sauce is too thick, just add water to thin it out.
When the dough has doubled in size, prepare a baking pan and create a round pizza shape, using your hands. If the dough is too sticky, just dust some flour on your hands and the dough as well.
Lastly top your pizza with tomato sauce, vegan mozzarella, veggies, and bake for 200 °C (400F) for about 15-20 minutes, or until crispy and golden. Enjoy warm.
