In a medium saucepan over medium-high heat, add cauliflower rice and water. Cover and cook until tender, stirring occasionally, about 5 minutes.
Stir in hot sauce, cream cheese, cheddar cheese, and ranch or blue cheese dressing. Continue stirring until hot and bubbly, about 5 minutes.
Serve hot with celery sticks or crackers. Or, transfer to a slow cooker and keep warm until serving time.
