Parmesan Roasted Green Beans With Mushrooms

This summer I'm trying to eat better and get more exercise.  In my effort toward improving my diet, I read the book, The Blood Sugar Solution by Mark Hyman.  The rules are no sugar, no flour, no processed foods, no alcohol, no caffeine (though I refuse to give up my tea).  That means I'm eating lots of veggies.  It's amazing how good things taste when you're not eating as much.  I saw this recipe on Pinterest.  You can find the original recipe here.  I added in mushrooms and some onion.  It was really delicious!
