Ugh, my roommate does the exact same thing and ruins every bag of frozen broccoli. I get so mad because it makes the whole kitchen smell like burnt food and it's such a waste. She just hits the button for frozen fries and walks away, no matter what's in there. Comes out looking like little pieces of charcoal every single time. I've stopped buying nice veggies because I know they'll just get nuked into sad, crunchy bits. It's like some people just hear "fryer" and think everything needs to be cooked to death.
