Have a list of foods that you should keep outside of the fridge if you want them to taste good.
Soft and moldy onions are useless. This happens to onions when you keep them in a cold place. Fresh onions that have not yet been unpeeled must not be put in the fridge or plastic bags. Fresh unpeeled onions should be stored in a ventilated place. The only case when you can keep onions in the cooler is if they are peeled. Use a covered container for the food.
