Preheat oven to 400 degrees.

Prepare pasta as directed on package.

Boil cauliflower until soft enough to puree; approximately 15-20 minutes. Allow to cool for 5-10 minutes; puree; add oil, mustard, nutmeg, salt and pepper, blend; then add stock and cheese a little bit at a time until fully incorporated (may add less liquid if desired). 

Place pasta in 8X8 baking dish. Pour over sauce, mix to combine; top with parmesan cheese. Bake for 20 minutes; until bubbly.

While baking, steam broccoli and slice pears.
