Looking for a healthy take on mac and cheese but with broccoli?

I adore this recipe and tend to drench it in cayenne pepper because I really enjoy cayenne. I see it as a mac and cheese dish, but with broccoli. Be ready if you prepare this, as there won't be any leftovers. I like the Rice Select - Royal Blend for wild rice.
