When reheating leftover meals in the microwave, I often take only a portion of the meal and heat it in a clean bowl or plate. But instead of using a piece of plastic wrap or paper towel to cover the food, I use an appropriately sized plastic or glass lid from my cupboard. The lid contains splatter messes, keeps the heat in and reduces additional waste from a piece of plastic or paper. Repurposed lids–try it!
