Please read post for more recipe details and photos. Adapted from White On Rice Couple, "Healthy" Broccoli Mac and Cheese Recipe. To make it all in one pot, prepare the cheese mixture in a stovetop safe and oven-proof pot or dutch oven (cast iron or similar pots). Then add the macaroni and the oven proof vessel goes directly into the oven. If you don't have an oven proof pot, then after you've made the cheese mixture with the pasta, just transfer it to an oven proof baking dish.
