I designed my house power system so I can have my microwave. I started with a microwave and designed from there. Microwaves do not destroy any food value or nutrients. They only vibrate the molecules. You know, we call it heat. A cotton sock filled with dry beans or rice heated for 1 to 3 minutes is real nice for my uncle sam's bad back. I take one to bed more than not.
It is really hard to cook for one person, and I have plenty leftover to reheat. Microwave wins.
