salad dressing. According to the information of the food website, salad dressing is used to mix mashed potatoes, and the mashed potatoes taste glutinous. When Thousand Island Sauce is added, the mashed potatoes are not evenly mixed, and the taste is not right, so it is not easy to be digested and absorbed by the human body. However, salad dressing can be directly and evenly applied to cooked potatoes, which makes them taste better and easier to be digested and absorbed by the human body.
