Sorry to be a wet blanket, but my suggestion would be to purchase a convection toaster oven instead.
Recently a high school student boiled two cups of water for senior science project. She watered one somewhat identical plant with water boiled on the stove and the other plant with boiled in the microwave. In ten days, the plant watered with the microwaved water was dead. If this is what happens to water, what about other foods. Something to think about.
