In the interest of full disclosure 🙃, after draining the pasta, I returned it to the pan, added the butter, mustard (generous measure, ~ 2-3X what the recipe specified), chili flakes, parsley and half the cheese over low heat and added a ladle of pasta cooking water to make enough light sauce to coat the cauliflower, which I added last. I used the Dry Breadcrumbs from Six Seasons that I had on hand. I halved the amount of butter since I used some oil to roast the cauliflower.
Edited to add that I will check out that Veg Literacy recipe as this is a good time of year for cauliflower around here.
