Add a bit of butter on the cut side of cheese before you put it back into the fridge to make it last longer. Put cheese in a wrap bag or container and seal to prevent it from hardening, place it in the warmest part of your fridge.

Wrap bananas before storing them and keep them away from other fruits as they contain a large amount of ethylene gas that makes other fruits spoil faster.
Use a paper towel on top of lettuce when storing it. It soaks in the moisture and makes sure the lettuce doesn’t get soggy too quickly.
