In double broiler, melt chocolate while popping the 3 bags of microwave popcorn. Put all popped corn in a large bowl. Pour the melted chocolate over it and stir with spatula or hands. Salt to give it a sweet and salty taste. Let cool...but don't put in fridge. It will make the popcorn stick to the bowl. Just put in a cool place. Then put in pretty bags with ribbon ties or in a plastic container.
