Cauliflower & Celery Root Purée with Sautéed Beet Greens

Whenever I go to my local farmers market, I’m always interested in finding new fruits and vegetables to try. Last weekend, I bought several small celery roots but had no clue what to do with them. By the way, contrary to what the name suggests, celery roots don’t actually grow at the bottom of bunches of celery. I know, the name fooled me, too.
