I had a college roommate who was a ballerina. Yes, a professional ballerina. She was tiny. She used to come home at night, grab a bag of frozen broccoli, dump its contents into a bowl, microwave it until it was hot, add butter, salt and pepper. That was her dinner.
Before long, of course, I began to want the same thing. I still eat it today, and it works for any type of veggie you like.
