Roasted Cauli Grilled Cheese

This recipe is from the book I got for Christmas called Relish, by Daphe Oz.  It's a grilled cheese sandwich unlike any I've ever made - it includes cauliflower, caramelized onions, arugula, cheddar cheese and a jalapeno aoili spread on multigrain bread!  Check out the recipe here.  

Here's a photo of how mine turned out, and oh my - was it good!
