It is common for us to have leftovers that we keep in the fridge for a a day or 2 until we have it consumed. But aside from leftovers, there are foods that go to waste. First is the expired canned goods. Second are the drinks like soda and fruit juice. There’s also the milk in the carton. If you stock on these food items, have a regular check of your food cabinet for the expiration date. It is a waste to open a can when it is already expired.
