We have been experimenting with alternative pizza bases recently. I had already tried a root potato pizza base a few years ago and we did one again recently. Something else we've been trying is removing the bread altogether, putting the meat on the bottom with vegetables and cheese on top
We took a chicken breast, flattened it out then fried it. After that it was topped with tomato sauce, vegetables and cheese. Since the base and vegetables were pre-cooked, it only needed to go in the oven until the cheese had melted.
