Combine the rolled oats, riced cauliflower, butter, cinnamon, salt, milk, and water in a bowl. Stir to combine.
Microwave for 3 minutes, stirring every minute or as often as needed to avoid the oats from boiling over (you'll need to stir more often toward the end).
Stir in the brown sugar and pecans just before serving.
