No clean up, 20 minutes, easy and healthy. Nothing more to say. This also will work with green beans, brussels sprouts, zucchini and summer squash, and mushrooms. I just change the seasoning a little (thyme with squash; rosemary with mushrooms and brussels sprouts) and otherwise, a great easy way to make a roasted flavor with no clean up. You may not get that dark caramelized color, but ... for a quick easy vegetable side dish, I love it.
