In a small bowl, combine the water, yeast, and sugar. Stir well and let it sit for about 10 minutes, or until it becomes foamy.
In a large bowl, whisk together the flour, xanthan gum or psyllium husk, and salt.
Make a well in the center of the flour mixture and pour in the yeast mixture and the olive oil. Stir with a wooden spoon until a sticky dough forms.
Transfer the dough to a lightly floured surface and knead it for about 15 minutes, adding more flour as needed to prevent it from sticking. The dough should be smooth and elastic, but not too dry or wet.
Place the dough in a lightly greased bowl and cover it with a damp cloth. Let it rise in a warm place for about an hour, or until it doubles in size.
Punch down the dough and divide it into two equal portions. You can use one portion right away or store it in the fridge or freezer for later use.
To shape the dough, roll it out on a floured surface into a thin circle, about 12 inches in diameter. You can also use your hands to stretch and press the dough into your desired shape.
Transfer the dough to a baking sheet or pizza stone that is lightly dusted with cornmeal or rice flour. Top it with your favorite sauce, cheese, and toppings.
Bake the pizza in a preheated oven at 425°F for about 15 to 20 minutes, or until the crust is golden and the cheese is melted.
To make the sauce, you can use store-bought pizza sauce or make your own by blending some tomatoes, garlic, basil, oregano, salt, and pepper in a blender or food processor. Spread the sauce evenly over the dough, leaving some space around the edges.
To add the cheese, you can use vegan cheese or dairy cheese, depending on your preference and dietary needs. Sprinkle the cheese generously over the sauce.
To add the toppings, you can use any vegetables, fruits, meats, or herbs that you like. Some of my favorites are mushrooms, olives, pineapple, ham, and basil. Arrange the toppings over the cheese as you wish.
