This is not really halloween, but have you ever made applesauce in the microwave? Peel and cut apples, put with a little water in a bowl, cover with plastic wrap and microwave till soft, then add a little cinnamon and sugar to taste and mash them up with a potato masher (the most fun part of all!). Now it is ready to eat. Kids love to mash things up, and even more fun when it is edible.
