Fry the onion until transparent. Add the rest of the ingredients and simmer for about 15 minutes. Set aside while you make the pizza base.
Sprinkle yeast, salt, sugar and oil over the warm water and let rest until yeast foams. Mix in flour and knead for about 10 minutes, then let rise until double. Roll the dough out to fit a cookie sheet for a large pizza pan. It will be pretty thin skin.
Pour on the sauce, cover with toppings (sliced onion, peppers, tomatos, olives, crumbled smoke tofu, veggies sauages, soy cheese or whatever you can think of).
Bake in 500F/260C for 15-20 minutes.
