In Shell - In a microwave safe bowl or cup, add egg and enough water to cover them. Add 1 tsp salt. Microwave for 3 minutes. Let sit for 1 minute. Then cook for another 3 minutes.
Carefully remove from the microwave and place egg in a bowl with cold water and ice cubes for approximately 5 minutes. Gently crack outside of the shell from the eggs, running it under cold water so it slides off and enjoy as desired.
Without Shell - Spray mug or cup with nonstick spray. Add just a dash of salt to the cup. Crack the egg into your cup and microwave for 15 seconds. Let sit for 1 minute, then cook for another 10-15 seconds until done to your liking. Remove and let sit for a minute or two before enjoying.
