I used to work 2 (sometimes 3) jobs at a time and found very little time to make meals (or do anything else!). I threw this dish together one day when I needed something quick and easy to heat up at lunchtime. It's become my favorite meal to take to work. I think any type of whitefish can be used. I tend to use catfish. I have used Dover Sole, but my coworkers couldn't stand the smell when I put it in the microwave! Amounts are approximate. If I feel it needs more potatoes or broccoli, I add more. Less butter can probably be used, but I like butter... Peel the potatoes if you want, but that would make it less quick and easy! Don't thaw the broccoli or it will get overdone and mushy. Feel free to experiment.
