Spread in a greased 9x 13 baking dish.
Put in large zip lock bag:
2 cups shredded cheddar cheese
2 t. Parmesan cheese
Smoosh everything around til well combined in the bag.
Sprinkle over cauliflower
Bake for 45 minutes, until the cauliflower is tender. I test it with a fork. Bake in lower half of oven so top doesn't over brown.
