Preheat oven to 350 degrees.

Cut bacon in 1 inch pieces and cook in a pan until crisp.

Meanwhile break cauliflower into bite size chunks and put in large casserole pan.

Mix cream cheese, sour cream, mayo, heavy cream, green onions and green chilies in a bowl with mixer until smooth. Pour over cauliflower and mix to coat.

Bake in pre-heated oven about 1 hour or until cauliflower is tender.

Sprinkle bacon and cheddar over cauliflower and return to oven 10 more minutes until cheese is melted.
