What's on the pizza?

The ingredients on the pizza are: pizza sauce, onion, butter, sticky cheese (for special use, otherwise the silk can't be pulled out), fruit, self-raising flour, eggs, milk, green peppers, bacon, peas, corn, mushrooms, monosodium glutamate, pepper, hot and sour juice, olive oil and so on. The usual practice of pizza is to use fermented round cakes covered with tomato sauce, cheese and other ingredients and bake them in the oven.
