I also dried all the leaves off the celery, chard, chickweed, dandelion, lambsquarters, and whatever else I could find in excess to use all winter, The kale is wonderfal as an addition to most meals all winter. It's organic, free and there was freezer space. Once we get a solar dryer(thank you for the link) we will dry so much more. Also we bought a greenhouse frame in the fall, once it's in place we will be able to allocate an area in it to grow greens for a much longer 'fresh food ' season.
