Rice the cauliflower, if needed. The riced cauliflower does not need to be cooked first.
Brown turkey in skillet and sprinkle with garlic powder, onion powder, salt and pepper.
Once browned, add in cauliflower, cream cheese, butter, heavy whipping cream, ¼ cup cheddar, ¼ cup mozzarella. Stir well to combine.
Pour into casserole dish. Sprinkle remaining cheese on top.
Bake 30 minutes.

Notes
Make the cauliflower rice ahead of time. Store the cooked cauliflower rice in the refrigerator for up to three days.Add extra cheese on top. The more cheese you use, the better it will taste.Make it as spicy as you want. My recipe is pretty mild, but it has a lot of room for creativity.
