1. Put the bread into a microwave-friendly tableware, sprinkle some water, cover it, and put it in the microwave for twenty seconds. Adding water and covering is to prevent the water from evaporating and the bread becoming too dry.

2. Cover the bread with microwave-safe plastic wrap, or cover it with a lid. Make sure to leave holes for ventilation. You can poke a few small holes in the plastic wrap with a toothpick. In this way, the moisture in the bread can be prevented from evaporating, and the heating time can be shortened and energy saved.
