Cauliflower Au Gratin

"This recipe for cauliflower au gratin is a delicious and simple recipe. It's a nice option to have on the holiday table for those who want to skip the mashed potatoes or stuffing because they're gluten-free or eating low carb. My teens get to carb load as much as they'd like, but my diabetic husband and I eat a lot lighter. This cauliflower au gratin is great for everyone because it is loaded with flavor, texture, and cheese. It's just 3.5 net carbs per serving which makes is great for keto and diabetic eating plans."
