Cook the cauliflower pieces in salted water until they are about 3/4 done. Drain and set aside.

Melt the butter in a high-sided skillet or saucepan. When hot, add the milk, cream, cheese, and garlic. Once everything is combined into a liquid mixture, add the cauliflower and pepper. Let it simmer for a few minutes. You can reserve some cheese for topping. Serve.
