Rainbow Cauliflower Gratin
Your guests will ooh and ahh at the rainbow of colors peeking through the blanket of cheese and breadcrumbs in this gorgeous gratin. Purple, orange, green and white cauliflower along with green beans are layered with a cheesy white sauce and then topped with breadcrumbs (and more cheese!). Bake until bubbling for an irresistible upgrade to your typical green bean casserole.
