Many of us see microwave cookery as blasphemous in and of itself. I've found though that a single scrambled egg will not suffer adversely from being cooked in the microwave. 1 Mug 1 Egg Crack egg into cup. Beat egg till smooth. You should be able to run the tines of a fork through it. Microwave for 40 seconds. It will expand pretty quickly, and look like it's going to spill over, it wont. This is a great and quick breakfast. Put it between to pieces of toast and you have a breakfast sandwich. You are going to have to soak (or scrub) the mug. The egg doesn't come out easily.
