Roasted Cauliflower w/ Preserved Lemon

If you have never had preserved lemons, I urge you to try them.You can make your own at home very easily, but I buy a huge jar from a Middle Eastern food store for so cheap, why bother?They have a unique flavor and are used mostly in Moroccan and Middle Eastern cooking.They are excellent in tagines and couscous, and one lemon goes a long way.I roast cauliflower often, sometimes with grapes,
