MAKE A MUG OMLETTE:
Cooking an omelette in a mug might not look like the real deal, but it's quick and simple. Whisk an egg, two egg whites, seasoning and some grated cheese or chopped ham. Pour the mixture into a greased mug and microwave it on high for one minute. Stir, then cook again on high for another minute.
Make stale cookies soft again by putting them in a plastic bag with a piece of bread. Leave it overnight, and magic! Good as new.
