Cheesy Cauliflower Casserole

Cheesy Cauliflower Casserole

This keto-friendly, low-carb, kid-friendly dish was all the rave when I served it at a Christmas dinner. I exchanged the pork rinds in the original recipe for gluten-free cheese crackers. I also added two cups of cooked quinoa for extra protein and crunch. This recipe involves several steps like roasting the cauliflower and preparing the sauce. It can easily be made ahead of time and refrigerated until ready to bake and serve. Original recipe found here,
