Whether it is on holidays, out of hospitality, or accidentally cooking too many dishes, we all have to face the problem of leftovers disposal. After all, it's a pity to dump a big table of dishes that you have worked so hard to make. However, inedible vegetables are not only easy to produce nitrite during storage, but also lose a lot of color and nutrients after repeated heating. Generally, the leftovers will become ugly and unpalatable if they are reheated. Therefore, it is best to eat vegetables at one meal without leftovers, especially cold vegetables.
