What is the cream cheese spaghetti sauce? . . White sauce depends on whether you are finished or semi-finished. If it is salty, use it directly. If it is a semi-finished product, add ham, green beans, boletus (crab-flavored mushrooms are also acceptable, do not add mushrooms and oyster mushrooms) and a small amount of dried basil leaves, cook and take out the pot. Remember to pair it with pasta or macaroni.
