According to the Joy of Cooking, you can microwave beets. I was running late for a BBQ on Sunday, and was planning to make a beet salad to bring. I didn't have an hour to roast 'em in the oven, so just this once I thought I'd try the microwave. Well. Not only do you end up with a disatrous mess, you also create wobbly, soft, tasteless beets. Now I know.
