Expert Tips

Mix and match and play around with other roasted vegetables. I have also done a version with mushrooms and asparagus that was out of this world.

Try adding crumbles of your favorite cheese to the top of the mushrooms, letting the warmth from the mushrooms melt the cheese. Gorgonzola is a great partner for this combination.
