Bring the cheese spread to room temperature while the broccoli and cauliflower cook.
Heat a large pan of water to a boil. Add a good amount of salt. Dump the broccoli florets in and blanch for 1 – 2 minutes. Immediately remove to an ice water bath. Drain well on paper towels and set aside.
Add the cauliflower to the same pan and cook until the cauliflower is very tender. This should take 15 minutes or so. You actually want to overcook it slightly…trust me.
Drain the cauliflower well and return to the pan. Add the cheese spread and mash with a potato masher. If the mixture seems too thick add a little milk and continue to mash until the mixture is almost smooth.
Fold in the broccoli. Check for seasoning and add salt and pepper if needed, (but you probably won’t need to). Serve.
