Pierce the potato on both sides with a fork
Microwave on high for 4 minutes
Take out and turn over
If adding cheese:
Microwave for 3 minutes
Take out and cut a V slice in the top
Add cheese
Microwave for 1 minute
Else:
Microwave for 4 minutes
I swap the potato to a new bowl after the first four minutes
so that the bowl doesn't get too hot.
