Cauliflower Pumpkin Casserole

Cauliflower Pumpkin Casserole

Try this inventive Cauliflower Pumpkin Casserole instead of plain old (and not-so-good for you) mac and cheese or cheesy potatoes au gratin.

It has some of our favorite flavors of both dishes, but in a much healthier all-veggie casserole.

The combination of roasted cauliflower, which gets nutty and sweet as it cooks, and a creamy cheddar cheese and pumpkin sauce gives it all the comfort of a cheesy casserole without the fat!
