Cut cauliflower into florets and add to a stockpot.
Cover with vegetable broth and water or until cauliflower is almost completely covered. Bring to a boil and cook until fork-tender, about 10-20 minutes.
Transfer the cooked cauliflower to a food processor or blender with a slotted spoon and add ½ cup of the hot broth, almond milk and spices and mustard. Blend until smooth, if too thick add in more broth.
Add in ½ cup of the grated cheese and blend again.
Pour the cauliflower cheese sauce over the pasta and mix together.
Pour into a baking dish (we used an 8”x8”) and sprinkle with the remaining grated cheese and bread crumbs.
Bake for 15 minutes and then place under the broiler until the top is golden brown.
