In a very large microwaveable mug, combine the macaroni, water, and salt. Stir to combine then place on a microwave safe plate.
Microwave in two minutes intervals, stirring in between, about 10 minutes total, until all the water is absorbed and the macaroni is tender.
Stir in the milk and cheese and microwave for 30 seconds, or until cheese is melted. Enjoy immediately.
